The Gerber NUK learner cup is the best sippy cup out there. My son refused all other cup but this one. The spout is soft and similar to a bottle nipple which makes the transition from bottle to cup so much easier. I tried all kinds of cups, hard spouts, soft straws, hard straws, other soft spouts, but nothing beat this product! We have about 5 of them and buy more when ever we see them!
