Boys bits and girls bits - can anyone recommend a simple book they've used (DS is 7)

Thats it really - DS is 7, he has a little brother and all our friends have boys too. He is curious about the differences between girls and boys, so time to help him understand.

Any recommendations appreciated, thanks.

Well it's old - I had it when I was at primary school but it's great -
www.amazon.co.uk/Body-Book-Non-fiction-Claire-Rayner/dp/0590556088
Covers everything from digestive system and growing up, to how a baby is conceived and born to getting old and dying in a really easy to understand and, I think, very nice way.

Thanks gourd, that looks great. The only books I'd seen were focussing on older boys I think, about 'why is my body changing'. This looks much more 'infant' focussed to start with. Ive ordered it from a second hand on line seller for 63p!
