My DD15 (just turned) stays at her Dad's every other weekend. So 4 nights a month. Sometimes has the odd dinner there mid week but that's not regular.
She shares a room with her 8 year old step sister (bunk beds). She has an older step brother who has his own room, then her dad and his wife have a room.
The past few months DD has been texting me whilst she is there asking for me to pick her up early. The usual reason is that her step sister is annoying her. Sometimes she says she's bored.
This is becoming more regular and we've now got to the point where she doesn't seem overly bothered about going at all. I've spoken to her and she says that her step sister just won't leave her alone and is very annoying. I've spoken to my ex (DD's dad) as he keeps getting annoyed that she is coming home early each time, or only going for 1 night. I've explained DD's reason for not wanting to go as much, and he has said that yes step sister can be annoying but they're family and DD just needs to deal with it. He says he has also spoken to his he step sister but DD says it hasn't changed anything.
I don't mind DD being at home 95% of the time but her Dad is now starting to say she is being unreasonable about her step sister, she just needs to suck it up and I must make her go.
What does everyone else think?
