This was amazing for a breastfed baby who won't take the bottle! Took him a few weeks, but now, we just hand him the cup and it fits nicely into his little hands. He'll drink out of the cup like a pro now! The material and construction is amazing, no sharp plastic for me to worry about him cutting his little mouth on. I literally just chuck one into the nappy bag, it'll get squished and whatnot, and it's still whole and hearty and ready to use when I take it out again!
Overall, a very well made and sturdy product. Very happy with this!
