I started taking my son to Gymboree classes just before 6 months and absolutely loved them. The classes themselves at that age are more for the moms to ask questions and be around other moms but it's still wonderful. As my son got older, the classes became more engaging for him and he looked forward to Gymboree every Tuesday morning. The classes consist of singing, circle time, parachute time, bubbles and just general play in their wonderful facility. Pricey, but worth it.
