We joined the gymnastics club just down the road from our house, and B has been taking the beginner class there since January. He LOVES it. He's taken gymnastics classes before, but they've always been four-week classes through the city rec program that were more like an hour of play than actual gymnastics. This club makes it fun for the beginners, but they seem to get pretty serious at the team level. He likes trampoline the best -- who wouldn't??
We started him so he could have a "thing" of his own, something he did without Z. I hope he keeps at it for awhile. I think the strength, agility and confidence it builds is really good for him.
