First try success!

I was blown away that my 7-month-old figured it out on the first day. I’ve heard babies can resist sippy cups but not this one. Plus, the 10oz size is perfect for growing babies. Love the straw and vent combo—no choking, no leaks.

Awesome quality and baby loves it

This cup is built to last! Our little girl drinks from it every day. The design is very ergonomic—even the handles help her hold it at just the right angle. Excellent product from a brand we now trust.
