My kids school offers a family sex ed program from... hmmm, I think it's prep? So the whole family can go along and there are guest speakers from an organisation that speak about puberty, reproduction and general health in an age appropriate manner. Sorry, can't remember the name of the organisation! Then the whole family plays games relevant to the topic. Sounds a bit naff, but it's a good way to break the ice and get families talking in an open way. I have never attended any of these evenings as I am very comfortable talking openly to my kids, but I have been told by other parents that they are great.

I answer any questions my kids have in a simple, honest way. The hardest part is to only answer the question and not offer further information. I find that my kids go away and process the information and then come back with more questions. My kids were 5 and 7 when DD2 was born... we had 7 months of LOTS of questions!! 'How did the baby get in your tummy, mummy?'!!!
