I haven't seen any men breastfeeding lately. Nor do fathers regularly go through post natal depression or suffer the other ailments of pregnancy. I suggest you talk to some mothers (or your own) before making such absurdly informed assertions.

Actually, post natal depression also affects men.

Not trying to imply that it doesn't. It is a stressful situation for everyone. But the rates in women are significantly higher. (Ironically being a stay at home mum can be isolating and it might be better for her health to go back to work...) One analysis also found a small be definite correlation between a mother being depressed and also the father. The incidence varies strongly depending on risk factors (smoking, obesity, poverty, trauma), form 10-25% in women, and about 5-10% in men (though men tend to under self report..).
