Why are men like this

How come when moms don't feel good or whatever the dad's get to just ignore us and the kiddo, get mad when we say there the reason the kid is jumping on us when they go over to us and start tickling the kid but when they are sick they expect to be able to lay around and do whatever but we still have to do everything as if we feel just fine. Mind you I have a headache that is making me feel nauseous tired sad a little dizzy
