When my DSD (4) is here, I usually do her hair because she likes me to, if I do something rather complex to her hair, I always take it out and put it in a pony tail (or something standard so it looks like OH may have done it!) before she goes home because I worry her mum won't like it. There are lots of little things like this, she likes to wear my perfume for example, and if we're going out I don't mind her using a little bit, but again I worry. Recently I was painting my toes and DSD asked me to do hers and I had to tell her that I wouldn't. I just really don't want to step on her mums toes. Anyone with experience of this kind of thing? Am I being too cautious? Or am I right to be?
