I have very inquisitive 3.8 year old boy/girl twins. Recently they have come very close to asking how babies get inside a lady's tummy (they were very interested in how they got out!)
I always try to honestly answer their questions & I like to be prepared so I would be grateful if anyone can recommend any appropriate books. Perhaps something you've found useful when discussing this subject with your own children? I'm looking for something that covers the basic mechanics in an age appropriate way.
Thanks in advance!
