My oldest son (now 2 1/2) as well as my youngest son (now 1) have both been going to this Gymboree since they were 8 weeks old. We LOVE this place and all! From age specific classes to open play to music classes we have taken advantage of all they have to offer and I truly feel that both my kids have benefited from Gymboree at each age level.
I work full time so it's most often my nanny who brings my sons to their classes. I'm sorry to miss all the fun, but I can see directly how much they are learning there ... cleaning up, climbing, songs ... they love it.
If you're looking for a great place to take your kids this is it.
