DD will be 12 in January and came in last night just before bed saying she thinks she's started her periods. Checked her pants and yep, she has. She's so upset - lots of tears about not wanting to grow up and she's not ready to turn into a woman. Tried to explain that it's just the beginning and doesn't mean she's not a child any longer. She didn't like the idea of having to wear a towel at night (refrained from telling her that she was lucky she didn't have the huge thick looped ones with the attractive belt, but didn't think it was the time for levity!) and her follow up comment after covering the basics was "is that it then?" made me wonder how much she actually understands about periods. She's always been big (over 99th percentile, is wearing 15-16 year old clothes in kids shops, and a size 12 in the shops she prefers)and now in retrospect I know I started preparing her far too early - she seems to have forgotten it all!!
Any advice?
