My son is about to turn 9. I've just been reading up on when you should talk to your children about puberty and it seems that 8 or 9 is a good time. We've had some basic discussions about it but I'd like to get a book that explains it all so that we can talk through it. I found a fab book for my niece once called 'Zits, glitz and body bitz' which looked really good but it was aimed at girls. I'd like something similar for boys - not too wordy, something he would be comfortable to read. Some of the books I've seen go into a lot of detail about blowjobs, sex details etc. I am not sure whether 9 is too young to have a book on these things or if it's better to tell them about them now while they're less embarrassed to ask questions.
Any suggestions?
