Mine are 11 and 8 now. With both kids, my wife was back at work within 6 weeks, and I’ve done most of the childcare since, being occasionally self employed.
As others have said, the traditional parent mother & toddler groups can be less than welcoming to blokes, though I persevered for the kids sake.
If you’re happy without social engagement other than your child (and the stw forum of course) then you’ll enjoy it.
I loved bringing them up as babies, in fact my wife jokes she never changed a nappy.
When they get to primary school, if you can still avoid working, then you get to go and ride your bike, after doing your housework first of course. 😉
In summary if you get the chance, do it. Spending time with my kids has been awesome.
