I saw your previous post, but didn't answer b/c we don't have Gymboree experience. But I saw your second post and feel bad that you had no answers....
so let me parallel Gymboree to baby swim lessons. I do have experience with that. I teach swim lessons to kids 4 and older.
In my opinion, the programs for babies are for the parents, not the babies. Babies are happy as long as they are loved and getting attention. Babies are happy playing with you at home, or at the park, or in the pool or bathtub with loving parents.
It's just my opinion, but I say save the money and play with your kids and get together with friends or neighbors to play.
All those sports, clubs, lessons come quickly enough and they are EXPENSIVE. When new parents ask me to teach their infant in the water, I politely decline and tell them to call me when their child is 4.
