I live with my DP - I have 2 dc, 14 & 6, and he has 2 dc, 11 & 7.
His dc come to stay with us every other weekend and a couple of nights during the week. We all rub along ok, the 2 youngest (both boys) get on like a house on fire, they bicker a bit, but only like little boys. In the main, they play really nicely together and have a lot of common interests.
The girls are mostly ok.... but my dd finds her really irritating. I know this is perfectly normal between a 14 & 11 year old - but it's causing a lot of tension in the house.
They share a room when dsd is here, but because she is that bit younger, there's certain stuff that dd can't watch on tv because it's not age appropriate when dsd is here. Dsd keeps dd awake half the night chatting to her.. oh, basically, she just really gets on her nerves.
What can I do? I get on fine with both the dsc mostly, but it's really upsetting to see dd who quite clearly feels she has her nose put out sometimes. She dreads them coming, and is now talking about finding stuff to do outside the house when they come.
