Good for babies
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

Great innovative product
This is a great product. Daughter loves these as it’s familiar to her bottle. Great for transitioning away from a bottle.

LOVE THIS
I love this product. It is so good! Fit our comotomo bottles perfectly. We used these while teaching my son how to use a straw & introducing water to him. Very durable, easy to clean. Personally I chose not to use these with milk. We only used them with water. Great quality and a good price!

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!

The baby doesn't want to use this bottle mouth
My baby doesn't want to use this bottle mouth, so it is unused.

Father Approved - Levi (my son) daily use
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.
