Re: daughter has no started puberty?
She's actually lucky. The other girls might tease her, but it's the girls who start puberty at age 10 or whatever who end up with a lot more health problems when they get older. I think I read several times that certain types of cancer are more prevalent among women who started their period before the age of 12 or something. I can't remember what it said. But I'm sure you'd find it if you did some research.
So tell her that the longer it takes, the better off she will be later.
