I realise I sound like I'm contradicting myself so just wanted to clarify. I have no problem in teaching small children about anatomy, periods, puberty etc. But I do have a problem with people teaching children about sex or allowing them to be exposed to inappropriate films etc. With regard to my brother and sil, they taught their four year old daughter that babies are.made when a mans sperm fertilises a woman's egg. I think its far too much for small children to understand and leads onto other questions.
