when did you talk to your daughters about sex and getting their periods? I have a ten year old going into fifth grade and she has the hormones going on and I'm thinking I should talk to her soon about starting her period at least. She will get sex ed in fifth grade so I can wait until before that to talk about the sex part. I'm her step mom and her grandmother, mother, and half-sister (18 with a 2yr old) all got pregnant as teens or very young and unmarked. I know that does follow later generations in some cases and don't want her to do anything she isn't ready for and to be knowledgeable, but don't want to force more knowledge on her than she is ready for.
