another problem with adding six year olds would be space cuz if u look at the membership for kids there are more 6 year olds than nething so that would demand more mats and lets be honest the 8 ,10, and 12 and unders would lose mat space and possibly 14 and 16 and unders and they need all the space they can get...tho it might seem like a great idea i think there are more problems than rewards
