Easy to assemble and use
Our baby HATES all baby bottles. As a last attempt, we purchased these sippy cups. Baby loves playing with this one! Easy to assemble and clean.ðð»

Perfect transition!
Weâve been using comotomo bottles from the beginning. I recently started looking for silicone sippy cups, but every one weâve tried has leaked. I found these by chance, and absolutely love that I donât have to buy whole new cups, and so far theyâve been leak-free! My son loves that he can hold it himself, unlike the 360 open cups that weâve had to hold for him, plus he can carry it around with him while he plays. So glad I found these!

NOT Spill Proof, but Still Great
Great converter from a bottle to a sippy cup, but only mostly spill proof. If the cup is sideways or upside down, the liquid will dribble out the slit in the top. And if your child squeezes the main squishy part of the bottle, it will squirt out!
Joseph Jaffke –
Great comotomo addition
My baby has used the comotomo bottles since the beginning & this sippy cup straw attachment has been a great transition! My daughter is able to drink water easily from it & itâs so easy to clean!

For the independent babies
My daughter loved holding her comotomo bottles when drinking milk. I wanted to introduce a sippy cup without buying all new bottles. These are awesome for traveling bc you donât have to pack multiple different bottles for different fluids. Can take one bottle and different nipples. Fit the bottle perfect.

Good transition; not so good for older baby
This is a nice transition to sippy cups as it attaches to the comotomo bottles. Unfortunately, my daughter bit holes in the spout right away which caused them to leak everywhere. She is a year and a half old.
