I took my first daughter when she was about 3mos old....had all the thoughts that it would be good "mommy and me" time, good way for her to "socialize", etc. Looking back, it was a total joke of a waste of money. No offense to you or anyone else...as I said, I did it wtih #1. But she got absolutely nothing out of it and half the time she would fall asleep or get hungry, etc and then half the class was missed. I wish I'd saved that $200 for a class after she was walking.
She took classes around 12mos (walking at that point) and again at 20mos and she absolutely had the time of her life at 20mos when she went. She did enjoy her time at 12mos, too. But again, I think they get more out of it when they are able to walk around, play on the equipment, etc.
That's just my 2cents. But I will say I got alot of cute pix of her at 3mos old burried in the ball pit! haha
