I think it's another patriarchy thing.
Socially, men seem to be able to get away still with leaving the house all day to go do their hobby once kids come along, but women don't.
So the football, the golf, the gaming, the skateboarding etc. gets the blame, and gets mocked for being childish, when that's not actually the problem, the problem is the men taking the piss.
Me and DP had our kid young, so we've hit 40 with a 16yo DD and have a lot of freedom again, while most of our friends still have young kids.
I find it very easy now to send a message to a couple of mates and say "Fancy a Pint", and be in the pub an hour later. Whereas DP struggles to get out with her friends even when organising weeks in advance because they've got no-one to babysit. Most of them don't need a babysitter, they have a husband, but that apparently isn't an option. A lot of our mates are in relationships with each other, so I gave my friends a bollocking about it in the pub a few months ago. I'd like to say things have improved, but not so much.
