How Do I Get Him To Understand and Help More?

Just because the old saying is "like father like son", that the father doesn't need to be laying around the house imitating his son. Let him go without clean dishes for dinner, or no clothes for a few days because he can't figure out the washing machine. Tell him you already have one baby to take care of and that if he is going to act like a child, then his mama can take care of him again. If he is off from work, there shouldn't even be a dirty gl in the sink or a speck of dust on the coffee table. I have been off work since 2002 and I do housework daily except wash my wife's underwear the way she wants them washed. Point your attention to the baby's needs and see if he can figure out the importance while being ignored. If he can't do it, then he needs to find a higher paying job to hire you a nanny or a housekeeper.
