Baby is three weeks old! She is probably dead beat. Maybe she wanted a bit of time to herself, and feeding the baby was an excellent excuse for removing herself from the room. I have done it myself!
As G2 says, if she pickes up on your disapproval of her, which looks as though it was there well before baby arrived, your visit will have been stressful for a mum who is only just finding her own routine.
She is your son's wife, what is his is hers. They must find their own balance of living. You can't impose yours. Look for her good points and emphasise those to yourself. She has lots, even if you have not noticed them yet. You brought up your son well, surely he has the ability to pick a suitable wife for himself?
