I have a 3 yo and 1yo. I'm not pregnant.
But my 3.5 yo has a book about bodies. It's mainly where the heart/lungs are. And what bones/muscles are for. He is really into it and tells everyone where their heart is.
There is a small section about babies growing in mummy's tummy. And I'm bit worried he'll start asking me how they got there or how they come out. I don't want to go into too much detail at this age as he's a bit young and will go around telling everyone!
Do you think it will occur to him to ask? Any suggestions on suitably vague answers I can give him?
