As soon as our children were old enough to ask questions about where babies came from(usually around the age of three), I answered them honestly in an age appropriate way. No subject was ever taboo in our home, and the dinner table conversations could be X rated at times! I did however have one proviso that the subject of sex was not alluded to if my Mother was visiting, she would have died, as she was the world's biggest prude!
Before I started secondary school my Mother was supposed to have told me about periods, and the where babies came from talk! She nearly died, and I said I knew all about it to save us both being embarrassed. I had a fairly hazy notion about both topics at the age of 11. Mum was very remiss because she left it to me to instruct my younger siblings, before they went to secondary school, which really wasn't on!
Sex education at my school, (all girls) was dealt with in the biology class when we were 15. It was HILARIOUS! The biology master was highly embarrassed when teaching us about the birds and the bees, we probably knew more about the topic than him, as sex was invented in the 60s.
To add to the poor guy's embarrassment we teased him, "Ooh Sir you are going as red as your tie!"
