So I've just gone back to work, ds is 9 months. I work every evening apart from monday and wednesday and the weekend 9-8 both days with a short gap in the middle. Dh mum been getting upset that their family don't see ds. Dh agreed for ds to stay over theirs without asking me. Now hes stayed over once she wants him every other weekend sunday night and Monday day. I'm not comfortable with this, I'd be happy for her to have him in the day and bring him back for bed but she wont take no for answer, just sort of bats around it. I really don't feel happy about him staying sunday and coming back Monday night as thats my full day with him. She could have him any time in the day but she wants him overnight. Dh doesn't understand how I feel as he works ridiculously long hours anyway. How can I make it clear I'm not comfortable with this and no means no? Or aibu?
