My dd is 7.5 yrs. I seem to have told her today what's what. Well, she asked and I answered her questions truthfully.
It was fine, but I hope I haven't talked about this too young to her. She seems curious, a bit incredulous, but has asked some well thought out follow up questions. It all came about because I mentioned periods a couple of months ago.
I didn't want to, but keep hearing that girls are starting so young these days and didn't want her frightened if anything happened early. She seems to have filed this away in her head and said no more until today. Do your dd's and ds's know about all this yet at this age?
