I think when I was in 5th grade....I got to see "The Movie".....all the little girls in my class AND OUR MOTHERS!!!!
We all had to stay after school and our mothers came in and we watched a movie that was all about our bodies....having periods, babies, etc. It was mortifying. It seems girls are starting younger now, I have several friends who have daughters/granddaughters that started at 9/10
You really need to talk to them separately. Your daughter will be embarassed if you talk to her in front of her brother, and it will be like talking to a wall.
I talked to my daughter, but chickened out with my son....I let my ex do it. (we were still married at the time).
My son didn't ask about condoms ....I don't think the commercials were on tv yet when he was that age. I found a Victoria's Secret catalog in his room under the bed....figured it was time for the talk.

. I think he was about 9.
You really don't have to get too specific when you first start the "talks"....the kids have a short attention span.
What 'til your daughter comes home and tells you someone she knows at school is pregnant and the discussion that involves! Mine was in 9th grade and I was on the board of directors of a home for unwed mothers ....with the girl's mother!!! That discussion was really tough. It when the whole range from keeping the baby, teen marriage, adoption, abortion, protection and abstinence. She tells me this while I'm driving.....I almost ran off the road.
And to think, you thought getting up for 2AM feedings were tough!
