This is the first time my baby has drank from a straw sippy cup and he did it correctly right away. The straw is easy for him to get his mouth around and use. He is still learning cups and learning to hold them but the handles are a good size for his 9month old hands. It is cute to look at and the bunny ear cap is great to prevent leaks or spilling. The weighted straw is good so even if he holds it at an angle, he will still get the water.
