Maybe you should try to do ALL of the things your wife does in the house and your son will want to become a dad? (And your girls will want to be whatever your wife has now the time to achieve, like becoming CEO?) There is no such thing as girls becoming boys and boys becoming girls. It all starts in the house with sharing the childcare, housecare jobs and the mental load.

Haha, I know what you try to prove here, but you are 100% wrong. I'm the one who spends most of the time with the kids. Their mom has a serious career. So no, this doesn't influence their preference.

Actually my kids don't want to do the job their mom is doing, since she's away/abroad all the time.

Nice try, but you are talking to the wrong person for that argument.
