Great product for transitioning babies away from baby nipples. Teaches them how to suck without choking! Handles are a plus (can be used without them if needed)

My baby had difficulty with other sippy cups but this, so much easier to use. He transitioned like nothing. Made it easier for him because he didn’t have to tilt the bottle. Also is great for space saving and you can use your bottles.

Loved these!! The transition from these to a regular straw was effortlessly! Definitely recommend for the littles learning to drink out of a straw!

I bought 5 different cups for my toddler to try to transition to a straw and he was never satisfied with any of them. I would also try drinking out of the other cups and it was even hard for me to do it I couldn’t imagine him doing it. So I eventually found these and they work great. Easy to sip out of, not so much effort like other cups, and no need to buy additional cups. I does leak just a little bit but it’s only when my toddler smashes the nipple on anything because water does stay inside of it at all times.

Love that it was a perfect replacement nipple instead of having to but brand new sippy cups. Faster flow but if your child likes to lay down to drink their bottle like mine the nipple can invert and cause a spill.

Honestly I want to love this because it fits perfectly in my babies old 4 oz bottles but she’s a baby and she’s going to throw things. This piece ALWAYS come out as soon as it hits the floor spilling water everywhere. The spout just doesn’t sit right on the baby bottles. It’s loose.
