I too have taken the same approach as N2L. As appropriate I have not denied the truth or down played it at all although I have used age appropriate language.

Maybe it was easier for me as we have brought/are bringing our kids up on a farm. They have seen the animals "making babies" as I describe it. I have never come out with the penis goes in the vagina or anything like that but I guess its pretty obvious when DD has been able to see the bull mount a cow etc. My girls have seen animals been born etc DD is 11 and I guess there is going to come a time when I need to discuss STD's and contreception with her. My husband does not agree with the approach I have taken (Eldest DD is from a previous relationship so she knew a little when we met) his not happy about me taking the same approach with our eldest DD. I had no idea what sex and periods were when I learnt at school in year 5 and I was so distressed by the thought. I really wished I had some prewarning what a period was or sex by my mother. I've heard of a number of older ladies not finding out until there Wedding night.
