Sorry if this has been done to death I did have a quick look.
Dd (5) has been asking exactly HOW the man's seed gets to the egg. I've answered as straight forwardly as I can but would like to get her a book about sex and conception we can look at together.
we had a great 70s one with mum being taken to hospital in a bubble car (still smiling) but it seems to be out of print.
Thanks for any recommendations!
