I gave my son Combi Step 2 cup but he didn't like it. And it was a disaster to make him drink water. But I thought it was too 'early' to give Step 3 cup to him. But since my elder daughter is using the Step 3 cup, and my son is so interested in that, so I let him try and the 1st time he tried it, he loved it. So since then, drinking water/juice is not a problem to my son anymore!
