Selfish husband

Why can't husband help their wife look after the baby? They always come back from work and go sleep directly. Looks like they are most tired people. Those man never think about their wife day and night look after their kids and newborn baby, do house chores. Some wife even not have enough sleep but their husband still complain their wife doing nothing. Those man is very selfish? Am I right? They can't said they tired from work and they should keep quiet help their wife look after baby.
