The transition from a bottle or sippy cup to an open cup is a major milestone, but it often comes with a trail of spilled milk, soaked shirts, and frustrated little ones. Finding an open cup designed for a toddler’s developing motor skills—one that is stable, safe, and sized for tiny hands—can make this phase less messy and more empowering for your child.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent years analyzing early childhood feeding gear, comparing silicone grades, weight distribution, and the ergonomics that actually help toddlers build independent drinking skills.
Whether you’re practicing baby-led weaning or replacing sippy cups entirely, the right choice depends on material, size, and stability. This guide breaks down the top options to help you find the best open cups for toddlers that will survive the learning curve and keep mealtime a little cleaner.
How To Choose The Best Open Cups For Toddlers
Selecting an open cup for your toddler isn’t just about picking the cutest design. The right cup supports oral development, encourages independence, and minimizes mess. Here are the essential factors to consider before adding one to your cart.
Material Matters: Silicone vs. Plastic vs. Plant-Based
Silicone is the gold standard for early training cups. It’s soft on gums, unbreakable, and typically free from BPA, lead, and phthalates. Plastic cups are lightweight and durable but can feel less stable. Plant-based options like sugarcane offer a more eco-friendly alternative without the chemical concerns of traditional plastics.
Size and Age Appropriateness
A 2 oz cup is perfect for babies 4-6 months old who are just starting to practice. A 4 oz cup works well for toddlers 6-18 months, offering enough liquid for meaningful practice without overwhelming them. The larger 7 oz cups are better suited for older toddlers who have mastered the basics and need a bigger serving.
Stability and Weighted Bases
Toddlers lack the fine motor control to hold a cup steady. A wide, weighted base significantly reduces the likelihood of tipping. Cups with tactile bumps or non-slip grips also help tiny hands maintain a secure hold, making the drinking motion more successful.

In‑Depth Reviews
1. ezpz Tiny Cup
The ezpz Tiny Cup stands out because it was developed and tested by a pediatric feeding specialist. Its design prioritizes oral and speech development by encouraging a natural, open-cup drinking posture. The interior angle of the cup ensures an even flow of liquid, which reduces the risk of gulping or choking, a common concern when transitioning from a bottle.
Built from 100% food-grade silicone, this cup is free from BPA, BPS, PVC, latex, and phthalates. The weighted base combined with tactile bumps on the exterior provides impressive topple resistance, which is essential for a baby’s first attempts at holding a cup.
The one-liter capacity is misleading; in practice, it holds a very small volume suitable for infant training. While the silicone is easy to clean in the dishwasher, some users have reported that hard water can leave mineral marks, so hand washing may preserve its appearance longer. It is safe for hot and cold liquids, making it suitable for warm milk or cooled tea.
Why it’s great
- Weighted base minimizes spills
- Ergonomic design supports oral development
- High-quality, non-toxic silicone
Good to know
- Very small capacity for older toddlers
- Hand washing recommended to avoid water spots
2. Moonkie Silicone Baby Cups
The Moonkie cup is engineered specifically for the earliest stages of open-cup drinking, recommended from 4 months. Its compact 2 oz size is ideal for tiny sips, helping to avoid overwhelming a baby with too much liquid at once. The interior has measurement lines that assist parents in portion control during baby-led weaning.
Made from premium platinum silicone, this cup is exceptionally soft, which is gentle on teething gums and new teeth. The weighted square base adds a surprising amount of stability for such a small cup, though it is still possible for a determined baby to tip it. The playful confetti sprinkles design is embedded within the silicone and does not fade or peel.
Some parents have noted that the silicone surface can feel a bit slippery when wet. A small aeration hole on the side can cause a minor leak if the cup is tilted aggressively. However, its durability is excellent—it doubles as a bath toy and survives being thrown without any damage. It is dishwasher safe for convenience.
Why it’s great
- Very small size ideal for 6-month-olds
- Soft silicone safe for teething gums
- Stable weighted base for size
Good to know
- Silicone can be slippery when wet
- Small aeration hole can cause minor leaks
3. Munchkin Splash Toddler Cups
The Munchkin Splash cups offer a versatile approach by including removable press-fit training lids. These lids direct the flow of liquid and minimize mess, making them a useful stepping stone for toddlers who are not quite ready for a fully open cup. The cups themselves are a practical 7 oz, suitable for water, milk, or juice.
Made from BPA-free plastic, these cups are lightweight and dishwasher safe. The four-pack includes a mix of colors (blue, green, pink, purple), and the cups nest together for compact storage. The modern design is visually appealing and fits well with most kitchen decor, and they are sturdy enough to survive being dropped repeatedly.
The main drawback is the training lid, which several users have noted is not entirely secure. It can pop off under pressure, defeating its purpose of containing messes. Additionally, the cup’s lightweight design makes it easy to knock over when used without the lid. For these reasons, it is best viewed as a transitional tool rather than a dedicated open cup.
Why it’s great
- Includes training lids for transition
- Value pack with 4 cups
- Nests for easy storage
Good to know
- Lid is not leak-proof and can pop off
- Lightweight and easy to knock over
4. Silicone Baby Training Cup Vemolea
The Vemolea training cup is distinguished by its integrated side handles, which are a significant help for toddlers with weak or developing grip strength. The ergonomic design reduces pressure on the wrist, making the drinking motion more comfortable and successful. This is especially beneficial for younger toddlers who are still mastering fine motor control.
Made from 100% food-grade silicone, the cup is non-toxic, lead-free, phthalate-free, and BPA-free. It is dishwasher, microwave, oven, and freezer safe, offering remarkable versatility for heating milk or cooling water. The 4 oz capacity is a balanced middle ground, providing enough liquid for a satisfying drink without being too heavy to hold.
The thick silicone construction is extremely durable and does not absorb flavors or odors, even after repeated use. It is also gentle on gums and can be used as a teether. The main drawback is that the handles are fixed and cannot be removed, which might limit the cup’s usefulness as your child grows and prefers a handleless cup.
Why it’s great
- Integrated handles aid grip strength
- Versatile safe for microwave and freezer
- Thick silicone does not absorb odors
Good to know
- Handles are not removable
- Slightly larger size can be heavy for very young infants
5. SUGARCANE Kids Cups Dulce Worlds
If you are looking for an eco-conscious alternative to plastic, the Dulce Worlds cups are made from 100% sugarcane, a renewable resource. They are USDA and LFGB certified, free from BPA, melamine, and PP, and offer a 70% carbon reduction compared to traditional plastic cups. For parents concerned about environmental impact, this is a leading choice.
The cups are lightweight but have a sturdy feel, with a wide base that provides decent stability for toddlers who are learning. They are dishwasher and microwave safe, and do not impart any strange taste or odor to beverages. The bright colors are attractive to children, and the 10 oz capacity is large enough for older toddlers and for use as a regular drinking cup.
The material, while durable, is not as soft as silicone. It can crack or chip if dropped on a hard surface from a significant height, though it is generally unbreakable for typical toddler use. It is best suited for toddlers who have already developed some coordination, as it is harder to grip than silicone and does not have a non-slip surface.
Why it’s great
- Made from renewable sugarcane
- Large capacity suitable for older kids
- Dishwasher and microwave safe
Good to know
- Harder material than silicone, less forgiving
- Can crack if dropped on hard floors
