I've been with DP for 5 years, he has a 8 year old DD from his previous relationship. We get on well but I don't parent her or try to. She has two lovely parents already for that.
However DP is very laid back, doesn't really see when his DD is being cheeky etc and can sometimes get quite defensive when you mention anything about his DD.
We live in a tiny 2 bed apartment, he let her go on a game the second she woke up at 6am and FaceTime her friend whilst playing, screaming and shouting and giggling at 6am waking us all up. He thought it was funny but got really annoyed with me when I bought it up. It wasn't just the fact she was FaceTiming and squealing, maybe the other girls parents didn't want their child being woken at 6am by FaceTime!
My problem is she will always interrupt me when I'm talking to her dad (they get plenty alone time) and he will always leave our conversation to answer her. I don't mind when it's about trivial stuff but sometimes it's about important things.
Am I being unreasonable in expecting him to tell her occasionally not to interrupt or ignore her until our conversation is finished? It's literally minutes
