My son is 4 in November (born 2015 obviously) and I would like to get him involved with a club, preferably in the Falkirk area. Any recommendations or ideas on how to make this happen? He has been going to a football class since he can walk and loves it. I've been out the game for a while but know it's changed a bit. Can he join a club at 4 for a run about? Cheers in advance.
