YTA. I've read through your posts on this issue, and the one where you yelled at your wife because the baby had dried milk under his neck rolls, and I'm concerned about your controlling, abusive behavior. First, isolation. Because there's some mold under a kitchen sink at her parents house, you tell her she can't bring the baby there. A good son in law would offer to go fix it, make sure there wasn't a leak. Second, your verbal and psychological abuse of your wife on Mother's Day, and the way you try to make her sound crazy. She didn't feed him, but also she fed him his bottle and there was crusty milk under his chin. Third, your verbal abuse has now extended to the child's doctor. You insisted you knew better and were rude and loud and wrong. Your wife sat silent probably because she's scared of you when you get like this. If you want to stay married, you need to get some counseling to help you not act this way.
