Swedish dads staying home with their babies...

How Swedish dads are taking care of their small babies is shown to the world as a good example. Well, of course it's important for dads to have a close relation to their kids and everything concerning babies doesn't necessarily have to be the responsibility of mums. Of course dads should change diapers and give food and look after their kids. That's natural, at least in Sweden. That's part of being a parent.

But...
I believe the roles are slightly different and there is no need for two people to be exactly identical. If the dad take care of everything, what do they need the mum for then? Only to give the man a possibility to reproduce himself?

One can ask why so many Swedish couples are divorcing? Isn't there a risk that there aren't families any longer, just two parents working parallell and in turns?

The arguments used for dads to stay home and take care of their babies is that it makes them sexy. That's not necessarily true...
