I took Yasin to kinder gym when he was about 2 which is a similar program run by gymnastic Australia.
He loved it - he always had an absolute blast playing on all the equipment and in the foam pit. He didn't join in the structured activities much but at the age he was I geuss that was to be expected. The was no pressure to join the activities, the teacher went through them and those that wanted to join in did so and the rest just did thier own thing.
Kinder Gym starts from 18 months - I don't think Yasin would have benefited from it much ealier although on the occasions I took Imran along he seemed to enjoy him self on the mats and so on.
