DD1 is 12/13 and in the national squad for a competetive sport, she has her first national comp about 3 hours away in a few weeks and is very nervous. Her coach has advised we go and stay down the night before as it will kick off early.
DD2 is 6 and whilst lovely a bit of a madam and they do not get on AT ALL.
I am a single parent, my XH is a bit of an arse, and works away. I do have friends locally, but my family are all away and woudnt be able to help.
XH's girlfriend is the XOW, and they have a DD who is 5 months older than my DD2 (yes it was very messy). At the time it was a nightmare and GF and I obviously had some drama.
However, 6 years later, the children all get on, her DD has SEN and my DD2 is a bit of her protector, they adore each other. GF/OW and I get on ok, we chat and are perfectly civil now, after all our DD's are sisters. I feel sorry for her because she is stuck with XH and I am free of him 
Anyway I asked if she would have DD2 overnight the night before and the day of the comp, she has had DD2 before for the day when XH is away. I have no worries she will look after her well and the girls will have a ball.
My friends and family are absolutely horrified that I asked her, though none of them were jumping in to help. Did I do wrong?? I find it so hard to ask for help at the best of times, this seemed as close to family looking after her as I was going to get. Is it odd??
