I specifically asked DH if he wanted to come to scan and could he definitely make it as they allocated a time when I would have DD. So his role was to see scan but also make sure DD isn't a PITA. He now says he has a conference call when the appointment starts.
It's too late to make other arrangements, do you think the hospital will be a bit annoyed? That's the main questions
Please also tell me IABU (which I am) to be peeved at DH for letting me down. I know it's work but I would have rescheduled the appointment if he'd said he wasn't sure or organised for someone to look after DD so that he had room for flexibility.
