C., I don't mean this as any kind of attack or judgment on your or your husband's parenting. But, from what you describe about your husband sleeping all day and your son going into the cupboards and feeding himself, and trashing the house, the use of language you don't like and the refusal to clean up after himself...It honestly sounds like your son is crying out for more structure, positive attention, routine and boundaries. He's only 4, and cannot be expected to make his own meals and entertain himself all day. I would strongly consider putting him in daycare every day, if your husband doesn't feel he's up to the task. I'd sit down with your husband and talk about how you two are going to divvy up the tasks to make sure your son is getting what he needs during his day.
