While we were eating our tea DS, who already knew about eggs and seeds etc decided to ask exactly how the Dad puts his seed into the mum. Well DH spluttered on his tea leaving me to explain, after giving him a brief explanation about special cuddles (and refusing his request to let him watch!!!) I said I would try and find a book which might explain things a bit better for him to read with his Dad... so... any recommendations? I looked at Mummy Laid and Egg but he is very science/factual minded so I think all the cartoony bits will just give him more questions so am thinking more information book than story book, but not something that will open more questions than it answers!!
