I did Gymboree and if you have the extra money their cool honestly their more for moms especially stay at home moms go socialize and brag about each other kids I think starting at crawling age is perfect because that's when kids get social and it's more for them my son went till he was 4 months then I put him back when he turned 2 and now he loves it ! A lot of the time in the classes when he was smaller he would just sleep
