saw the discussion on gyms...just to share, i brought my boy to my gym..the activities are quite fun, but i think pretty similar to other gyms (based on description i read from the discussions). the plus point is that if you have toys r us card, the trial is only $5. Very worth it. The only negative thing that happened was that my boy was a little cranky as he was very sleepy....then they wanted him to have a try the forward roll...so while he was crying, they just flipped him over....which i thought wasnt quite good, cz i personally felt that the instructor should have supported his neck, which didnt happen.
Nevertheless, may still sign up package in the long run, cz near my place. wanna try out tumbletots first cz i heard they are quite good too
