These were great for my baby up until she got to the age where she started squeezing the bottle, squirting her drink everywhere and biting the nipple lol however the bottle itself doesn’t leak

My son Levi uses this every day. At first, he didn’t like it, but now it’s part of his daily routine. No complaints if he refuses milk, it’s only because he’s full, not because of the product. Plus, it’s very easy to clean, which I really appreciate.

We’ve been using comotomo bottles from the beginning. I recently started looking for silicone sippy cups, but every one we’ve tried has leaked. I found these by chance, and absolutely love that I don’t have to buy whole new cups, and so far they’ve been leak-free! My son loves that he can hold it himself, unlike the 360 open cups that we’ve had to hold for him, plus he can carry it around with him while he plays. So glad I found these!

Great for transitioning from bottles to sippy cups. Took awhile for my daughter to get the hang of it, but once she did, she preferred them over the plastic ones.
