Wasn't really sure where to put this so went for Aibu as always seems to get good answers.
So my 4 year old son has asked a few times now how mummies and daddies make babies, where they come from etc? It always seems to be at bedtime so have fobbed him off a bit and said we will talk about it tomorrow etc but what do I say? He has asked several times now so I need to give him an answer but not sure how to make it age appropriate???
