Sorry hun, not too sure about the baby talk, but maybe it's a habit that he'll just have to break himself. As for the swearing... I guess all I can say is lead by example. Do your absolute best to make sure there are no bad words on TV or in video games, but especially coming out of you and dh. Maybe you could take something away each time he says a bad word? It's such a difficult age and I'm not quite there yet with Peyton so I don't really have much advice. Good luck though, hopefully someone on here will be able to help you out.
