Ds #1 drank juice for awhile and then turned to water and won't even try juice now. Ds #2 never drank juice, only water - and he still won't. I think I tried once and he just didn't like it. Now, Dd (5 mo) loves water. I can't keep her out of mine! I don't think I will even try juice when the time comes. Besides, their ped says its just empty calories anyways.
