I need a recommendation for a 'how babies are made' book for 4 year old

[NoseyNooNoo]

My 4yr old is very interested in how babies are made. I have tried to be honest without going into the finer details of sexual intercourse.

Does anyone have any book recommendations? She is still at nursery but reads very well for a 4 year old - already on the blue reading band (if that makes sense to anyone).

"where did I come from?" by Peter Mayle..nice cartoony style without much of the more "adult" content!

I am expecting DC#3 in a few weeks, so have been going through this with DS (5). I got 'Mummy laid an egg' and 'Where Willy Went', along with an ancient copy of 'The Body Book', which I had as a child.

None of them are perfect, but they don't have to be - it's just something to give you a few prompts when you're answering all those questions. Mind you, I'm having a hard time convincing DS that sperm don't really wear race numbers on their backs and say "we was robbed" when being beaten to the egg...

Peter and Caroline is an old fashioned but rather nice book from the 1950s. Covers changes to the body, how babies grow and are made in a very gentle way.
