The only transitioning bottle that works
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.
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.
My neighbor swore by Thyseed so I gave it a shot. Super happy I did. My baby picked it up quickly, and I love how secure the lid is. It doesn’t leak in the bag, which is a total win. Definitely recommending this to other mom friends now.
I was skeptical at first, but wow—this sippy cup is AMAZING. My 8-month-old took to it on the first try. The soft, breast-like spout really made the transition from bottle smooth. You can tell it’s made from quality materials. It’s leakproof, sturdy, and just feels premium. I’ll definitely be checking out other Thyseed products. Highly recommended!
