Isn't it convenient that nature has already placed us in our respective roles and given us the necessary strengths to handle our different but equally important roles?

It's such a tragedy that one might feel compelled to weigh the burdens of motherhood vs fatherhood as if either side had a choice in the matter or as if there is some kind of competition to be won.

The only roles that nature put you into are carrying the baby and giving birth (and possibly breastfeeding). Everything else can be done by both parents.

(I'm a dad, who does do half of everything with the kids. It is possible, it's just a lot of stuff to do.)

I doubt OP would agree with your assessment nor your use of the word "only" but I appreciate you. ;)
