My DS has been going to swimming for 1/2 hr a week since he was 5mths old. He loves it. He's been doing well without me in the water with him for the last two terms.
I try and take him for an extra swim another day a week.
We also attend one playgroup and occasionally another one.
I am thinking about enrolling him in a music group next term.
If the dance group one of his girl friends attends wasn't on at the same time as swimming I'd have happily taken him along. I guess I don't care if he's girly just if he's happy.........
BTW I am a SAHM and we live on a property and he is my only living child. For this reason I seek out activities more than I possibly would had his sister lived.
