I have a 7 year old girl and a 5 year old boy. I also have a mindstorms kit. I don't think my daughter is ready for it yet. She plays with other basic lego's and until I see that shes putting things together with more intent and focus I don't think she's ready. But you know how kids are, they grow in spurts. So she could surprise me soon enough. Otherwise I think another year or so. Also you might run the risk of spoiling it for her in the future if she doesn't have success with it now. She might think it's not fun and dis it later on. Every kid is different, but most of the 7 year olds I know don't seem like they're mature enough for the focus required for that kit. Maybe a good thing to do would be to get a lego kit that comes with similar pieces but comes with a manual for building a couple specific things, and see if she can do that by herself. If so you could graduate her slowly. Definitely do not turn her loose alone on that mindstorms kit though. It needs to be explained quite intensely.
