Best Training Sippy Cup When Spills Are the Problem

The best training sippy cup is the Nuby Clik-It Grip N' Sip, a 3-pack of soft-spout cups holding 10 oz each and rated from 4 months up, which makes it the earliest-starting and highest-capacity pick in this group. If you'd rather skip spouts entirely and go straight to an open drinking edge, the Munchkin Miracle 360 in 7 oz is the cup to buy instead.

Most guides for this category compare spill-proofing. Every one of these six listings claims to be spill-proof, so that claim sorts nothing. What actually splits the field is the drinking mechanism and the stated starting age: 4 months for a soft spout, 6 months for a straw, 8 months for the larger NUK. Match those two things to your baby and the rest is packaging.

Best training sippy cup at a glance

How I screened this category down to six cups

I started from the cups sold under Solid Feeding, then compared the published listing data side by side rather than the marketing headlines. Three data points did the sorting: the stated minimum age, the capacity in ounces, and how many cups come in the box.

Here's what that surfaced. Age ranges are not interchangeable. One cup starts at 4 months, two start at 6 months, one starts at 8 months. Buy the wrong one and it sits in a cupboard for a season.

Capacity varies more than you'd guess: 5 oz at the low end, 10 oz at the top. That's double. For a baby taking a few sips of water with lunch, 5 oz is plenty. For a toddler drinking milk at every meal, it means refills.

Pack size decided several placements. Two of the six ship as three cups, two ship as pairs, and two ship as a single cup. A best training sippy cup recommendation has to account for that, because one cup in the house means one cup in the dishwasher and nothing to drink from.

What I cut: anything without a published capacity figure, and anything where the listing didn't state an age. Both are the numbers that decide whether the cup works, so a listing that omits them isn't giving you enough to buy on.

1. Nuby Clik-It Grip N' Sip Soft Spout No-Spill Training — Best overall

Three 10 oz cups, a soft silicone spout and the earliest stated start age here, which covers the whole first year of cup practice.

Best for: a first cup at four months, with spare cups on hand Skip it if: you want to skip spouts and go straight to an open rim

Two figures put this cup first. It holds 10 oz, tying the largest capacity in the set, and it arrives as three cups rather than one or two. That combination is unique here. Nuby lists it from 4+ months, four months earlier than the NUK 10 oz cup and two months earlier than everything else in this group.

Nuby says the silicone spout is gentle on gums and teeth, and that a built-in TOUCH-FLO valve opens only when the child sips. The listing also describes a Clik-It lid and a contoured base with handles sized for small hands. The set ships in aqua, purple and pink, which is genuinely useful when two children are drinking at the same table.

At 3 oz for the whole listed weight it's the lightest entry here, and it's the second-cheapest of the six. Top-rack dishwasher safe, per the listing.

The trade-off is the spout itself. A valve and a spout mean parts to scrub, and a spout is a stage your child eventually has to leave behind. The Munchkin skips that stage entirely. This is also the only pick with no age ceiling guidance beyond "4+ months", so you're judging readiness yourself.

Pros:

• Three cups per box, most in this set
• 10 oz capacity, tied largest here
• Earliest stated start age at 4+ months
• Second-cheapest of the six picks
• Three colours for multi-child households

Cons:

• Valve and spout add parts to clean
• Spout stage still has to be unlearned later
• Only two sellers list it
• Listed count field reads 0, not 3

2. Dr. Brown's Milestones Baby's First Straw Cup — Best budget pick

The cheapest cup here and the only one with a weighted straw, so it drinks at any tilt angle.

Best for: a baby who tips the cup at every angle Skip it if: you need more than one cup in rotation

This is the cheapest of the six and it earns the placement on one mechanical detail. Dr. Brown's says the soft silicone straw is weighted, so it moves with the liquid and the baby can tip and sip in any direction. Fixed straws lose contact with the drink the moment a cup goes sideways, which is exactly what a nine-month-old does.

Capacity is 9 oz, second-largest here. The listing describes removable side-grip handles and a contoured body, plus a sliding lid that stores the straw for travel. Measuring marks on the cup let you see how much has gone down, which none of the other five listings mention.

At 4.66 oz it sits mid-pack for weight. It's the only cup in this group with printed measurement markings, and it's also the pick with the strongest sales position across the whole set.

The obvious limitation is quantity: this is a single cup, 1-pack, dark blue only. Buy it and there's no backup while it's drying. Only one seller lists it. And straws are harder to clean thoroughly than a rim, so budget for a straw brush.

Pros:

• Cheapest pick in this comparison
• Weighted straw drinks at any angle
• 9 oz capacity, second-largest here
• Measuring marks show intake
• Removable handles and sliding travel lid

Cons:

• Single cup only, no spare
• One seller carries the listing
• Straw needs a dedicated brush
• One colour choice, dark blue

3. NUK Learner Cup, 8+ Months — Most versatile

A 10 oz soft-spout pair with removable handles and an air vent, built for a baby already drinking real volume.

Best for: an eight-month-old already drinking real volume Skip it if: your baby is younger than eight months

The versatility here comes from the handles. NUK says the anti-slip grips are removable as baby grows, so the same 10 oz cup works for a two-handed eight-month-old and later for a toddler who wants a plain beaker. That's two stages from one purchase, and only this cup and the Dr. Brown's list removable handles.

Capacity ties the Nuby at 10 oz, and it ships as a pair. NUK also lists an air vent to reduce swallowed air, plus a spill-proof soft spout described as gentle on gums, with liquids flowing when sipped. BPA-free and dishwasher-safe per the listing. Fun fruits and animals print, sold as an Amazon Exclusive collection.

Where it separates from the Nuby is the age floor. This one is recommended from 8 months, so it's a second cup rather than a first. It's also one of the two most expensive picks in the group.

The trade-offs: two cups instead of three, a higher price position than the Nuby for the same 10 oz, and at 6.35 oz it's the heaviest of the soft-spout options. If your baby isn't yet eight months, the NUK 6+ cup or the Nuby is the buy.

Pros:

• 10 oz capacity, tied largest here
• Handles remove as the child grows
• Air vent to reduce swallowed air
• Two cups per pack
• Dishwasher-safe and BPA-free per listing

Cons:

• Not recommended below 8 months
• Among the most expensive picks here
• Heaviest soft-spout cup at 6.35 oz
• Two cups where Nuby gives three

4. The First Years Squeeze & Sip Straw Cups — Best for heavy use

Three 7 oz squeezable cups, so you control the first sip and the child learns what a straw does.

Best for: parent-assisted straw practice at the table Skip it if: you want the baby drinking unaided from day one

This is the only cup in the group where the parent does part of the work. The First Years says you squeeze the bottle and the child sips through the silicone straw, which has a valve controlling the flow. For a baby who hasn't worked out suction yet, that removes the hardest part of learning a straw.

Three cups per box, 7 oz each, listed from 6 months and up. The listing calls it BPA-free and top-rack dishwasher safe, and says the same cup carries on as a regular toddler cup once training is done. At 2.69 oz for the listed weight it's the lightest thing here, and the slim 6 x 2.5 x 2.5 in body is the narrowest, which matters for a diaper bag side pocket.

It's also the second-fastest seller of these six and sits roughly mid-range on price.

The catch is the squeeze mechanism. It's a teaching aid, not a self-serve cup, so early on you're at the table doing the squeezing. Colours are assigned rather than chosen, per the listing note. And 7 oz is 3 oz less than the Nuby, so a thirsty toddler will want a refill.

Pros:

• Three cups per box
• Parent-squeeze design teaches suction
• Lightest listed weight here at 2.69 oz
• Slimmest body at 2.5 in wide
• Continues as a plain toddler cup

Cons:

• Needs a parent to squeeze at first
• 7 oz, well below the 10 oz picks
• Bottle colours not guaranteed per listing
• Straw and valve both need cleaning

5. NUK Learner Cup, 6+ Months — Best for families

A small 5 oz pair with removable anti-slip handles, sized for a baby taking sips rather than drinks.

Best for: a six-month-old starting on small volumes Skip it if: your baby drains more than 5 oz per sitting

At 5 oz this is the smallest cup in the group, and that's the point. A six-month-old learning to hold a cup does better with a light one, and a full 10 oz cup is heavy for two new hands. NUK lists it from 6 months, two months earlier than its 10 oz sibling.

Mechanically it's the same NUK design: a spill-proof soft spout described as gentle on gums, an air vent to reduce swallowed air, and easy-grip anti-slip handles that come off as baby grows. Two cups per pack in the neutral Timeless colourway, which is the least child-themed finish here if you'd rather the cup didn't clash with the kitchen. BPA-free and dishwasher safe, per the listing.

Price sits in the middle of this set, and the listed weight is 5.6 oz.

The obvious limit is volume. Half the capacity of the Nuby means twice the refills once your child is genuinely drinking, and that arrives fast. Two cups rather than three, and a plain colourway that some kids find less appealing than the fruit print on the 8+ version. Consider it a starter you'll outgrow, not a cup for the whole first year.

Pros:

• Lightest fill volume, easiest for new hands
• Stated from 6 months
• Handles remove as the child grows
• Air vent to reduce swallowed air
• Neutral colourway across the pair

Cons:

• 5 oz is the smallest capacity here
• Refills needed once intake grows
• Two cups, not three
• Least playful design of the NUK pair

6. Munchkin® Miracle® 360 Trainer Sippy Cup with Handles — Best premium

The only spoutless, strawless cup here: a 360° rim that teaches drinking from an actual cup edge.

Best for: skipping the spout stage entirely Skip it if: you want the cheapest route to a working cup

Every other pick here trains a spout or a straw. This one trains a rim. Munchkin says the 360-degree drinking edge lets a child sip from anywhere around the top and seals automatically when they stop, and the listing describes the spoutless design as supporting normal mouth muscle development by having kids practise drinking like a regular cup.

Two 7 oz cups per pack, listed from 6 months up, in blue and green. Munchkin says there are no extra valves or separate straw parts, which is a genuine advantage over the four cups here that have one or the other. Easy-grip handles for small hands, BPA-free per the listing.

It's the most expensive pick of the six and the only one with a single seller. It's also the oldest design here, released in 2014, which cuts both ways: long production run, but nothing new in the box.

The real cost is spillage during learning. A 360 rim seals when idle, but an upended cup with a child's mouth on the edge behaves differently from a valved spout. 7 oz also puts it 3 oz behind the Nuby, and you get two cups for the highest price in the group.

Pros:

• Only spoutless design in this comparison
• No separate straw or valve parts
• Seals automatically between sips
• Trains open-cup drinking directly
• Handles sized for small hands

Cons:

• Most expensive pick here
• 7 oz versus 10 oz on the top picks
• Two cups at the highest price position
• Single seller on the listing
• Learning curve is messier than a spout

Spout, straw or spoutless rim: which should you start with?

This is the decision. Everything else is detail.

1. Soft spout. Closest to a bottle nipple, so the switch is easiest. Nuby lists 4+ months, NUK lists 6+ or 8+. Both describe a valve or vent controlling flow. The catch: your child eventually has to unlearn it.
2. Straw. Skips the spout stage. Requires suction, which not every six-month-old has figured out. The First Years hands you a squeeze bottle to bridge that gap; Dr. Brown's weights the straw so it works at any tilt.
3. Spoutless 360° rim. The Munchkin trains cup drinking directly, with no intermediate step. Messiest to learn, cleanest long-term habit.

If your baby is under six months, the choice is made for you: the Nuby is the only pick here rated from 4 months.

If your baby is already six months or more, I'd start with a straw or the 360 rim and skip a stage. Both routes are represented in this set at three different price positions.

How much capacity does a training cup actually need?

The spread across these six is 5 oz to 10 oz, and that gap matters more than it looks on paper.

• 5 oz (NUK 6+): a light cup for a baby taking a few sips of water with solids.
• 7 oz (First Years, Munchkin): enough for a full drink at a meal without being heavy.
• 9 oz (Dr. Brown's): headroom for a toddler who drinks properly.
• 10 oz (Nuby, NUK 8+): the most in this set, and Nuby lists 10 oz as 300 mL.

Weight follows capacity, and empty weight is a poor guide anyway. What fills the cup is what your child lifts. A 10 oz cup of milk is a real load for two hands still learning coordination.

My rule of thumb: start small, size up once. Two 5 oz cups plus a later 10 oz pair is a better sequence than starting big and watching your child give up on a cup that's too heavy to hold at the rim.

What does a bigger pack really buy you?

Pack size is the least glamorous number on these listings and the one that changes daily life most.

Two picks ship three cups: the Nuby and the First Years. Two ship pairs: both NUK cups and the Munchkin. Two ship single cups: Dr. Brown's and, going by the listing, the Munchkin arrives as one item in a 2-pack box.

A single cup means one cup in the dishwasher and nothing to drink from while it's in there. Training cups get lost, chewed and left at grandparents' houses. Three cups is a rotation. One cup is a single point of failure.

That's a large part of why the Nuby leads. Three 10 oz cups at the second-cheapest position in this set is more useful cup for the money than two cups at the highest position, even before you look at the spout.

What the listings don't tell you about cleaning

All six say dishwasher safe, four of them specifically top rack. None of them tell you how many pieces come apart, and that's the thing you'll actually feel at 8pm.

Count the parts by mechanism. A valved soft spout is a cup, a lid, a spout and a valve. A straw cup is a cup, a lid, a straw and often a valve, and the straw needs its own brush. The Munchkin's listing says no extra valves or parts, which is the shortest wash of the six.

Two more gaps worth knowing. No listing here states a warranty, so treat these as consumables rather than lifetime purchases. And none states whether the cups are safe for hot liquids or sterilising, so if that matters, check the packaging before you assume.

Straws also hide residue where you can't see it. Milk in a straw cup that sat in a bag for a few hours is the one scenario where the Munchkin's parts count pays off.

When a different cup wins

The best training sippy cup for most families is the Nuby, but three specific situations flip it.

• Your child is already eight months or older. Skip the 4-month spout. The NUK 8+ gives you the same 10 oz with removable handles, or the Munchkin skips spouts altogether.
• Your child keeps tipping the cup sideways. Buy the Dr. Brown's. It's the only weighted straw here, and it's the cheapest pick in the set.
• You want to avoid a spout stage completely. The Munchkin Miracle 360 is the only spoutless option in this comparison, and it's the one to buy if dentist-style cup habits are your priority.

One more flip. If your child hasn't mastered suction and gets frustrated with a straw, the First Years squeeze design is the only cup here where you can start the flow for them. That's a teaching tool, and it's a better first straw than a straw they can't work.

The verdict

The Nuby Clik-It Grip N' Sip is the best training sippy cup for most families, and the margin isn't close on paper: three cups per box, 10 oz each, a soft silicone spout with a valve that Nuby says opens only on a sip, and a stated start at 4+ months. Nothing else here starts that early, and nothing else combines the largest capacity in the set with the largest pack at the second-cheapest position.

Two conditions change the answer. If your baby is already past eight months, the head start on age is worth nothing, and the NUK Learner Cup 8+ gives you the same 10 oz with handles that come off as your child grows. And if you'd rather your child never learns a spout, the Munchkin Miracle 360 is the only spoutless cup in this comparison, with a 360-degree rim that Munchkin says supports normal mouth muscle development.

The runner-up's specific advantage is worth naming. Dr. Brown's Baby's First Straw Cup is the cheapest of the six and the only one with a weighted straw, so a baby can tip the cup in any direction and still get a drink. It also prints measuring marks on the body, which no other listing here mentions. Buy it as a second cup even if the Nuby is your first.

FAQ

Is a training sippy cup worth buying at all?

A training sippy cup is worth buying if the alternative is a bottle at twelve months. Every listing here frames the cup as a bridge from bottle or breast to an open cup, and the mechanisms differ: soft spout, straw, or 360-degree rim. Cheap enough to try two, and a spare cup means one is always clean.

How much does a training sippy cup cost compared to a regular bottle?

What a training sippy cup costs varies mainly with pack size, not sophistication. In this set, the cheapest pick is a single 9 oz straw cup, while the second-cheapest is a 3-pack of 10 oz spout cups. The most expensive is a 2-pack. Per cup, the multipacks are the better value, so check the count before comparing.

What capacity should I look for in a training cup?

The capacity you look for tracks your child's actual intake. These six range from 5 oz to 10 oz. Start at 5 oz for a six-month-old taking sips alongside solids, since a lighter full cup is easier to lift. Move to 9 oz or 10 oz once your child drinks a proper glassful at a meal.

Nuby Clik-It or Munchkin Miracle 360: which should I pick?

Nuby Clik-It or Munchkin comes down to whether you want a spout stage. Nuby gives three 10 oz cups from 4 months with a valved soft spout, and it's the cheaper of the two. Munchkin gives two 7 oz cups with a spoutless 360-degree rim from 6 months, at the highest price position here, and skips the spout entirely.

What mistake do parents make with training cups?

The mistake parents make with training cups is buying one cup. Two of these picks ship as single cups, and a single cup in the dishwasher leaves your child with nothing. The second mistake is ignoring the stated age: 4 months, 6 months and 8 months all appear across these six, and they're not interchangeable.

Pick the mechanism first, then the size, then count the cups in the box. If you want one decision made for you, the Nuby 3-pack covers the widest age window of anything here and gives you two spares from day one, which is the difference between a cup habit that sticks and a cup that's always in the sink. Buy a second cup with a different mechanism a month later. Watching which one your child reaches for tells you more about the next purchase than any specification list, including this one.
