Does anyone have a suggestion for a toddler to do gymnastics in North London/Watford area he is nearly 3. He is so active and has fantastic balance and a lot of potential, just found out we have a gymnastics champion in the family (great grandad) so want to give him a chance to see if he is any good. Need to do this in the evening or weekend. Where do I start and is it healthy to try and do this with a toddler or should I wait till he is older?
