I'm a dad of 2 boys, 3 and 1 years and we go to a group for dads and their little ones called Men Behaving Dadly. It meets on the first saturday of the month in st marks hall on Boutflower Road, Clapham Junction and kids tend to be from babies up to 5 yrs ish.
It is informal and includes coffee, bacon and egg butties for dads, fruit for kids and lots of toys out in the hall. The hall is well equipped for kids activities so there is lots of energetic play. My wife loves the morning off and I like the time with the boys and meeting up with a really friendly bunch of dads in the same situation as me, and the bacon butty goes down well too!
It is on this saturday, 1st december at 930 till just before lunch.
Next one after that is sat 5th jan. It doesnt charge, just a contribution towards breakfast.
