Any insight? He'll be 4 in a few weeks, he's always been a mama's boy, but for a while now he's just being outright MEAN to his dad. I get that parental preference is a common thing, but the level of hostility is starting to really tick me off. He regularly pushes him away if he tries to get a hug or cuddles, will tell him to stop talking (even when he's not even talking to LO) and this morning he yelled at DH to go to work and never come back, and the only thing DH had done was walk into the room.

I have talked to LO until I'm blue in the face about how loving his dad doesn't mean he loves me any less, but nothing is working and it is starting to wreck DH. And he's getting to the point where he doesn't even want to try with LO anymore, which just makes the situation worse.
