To think we have to go through this conversation soon is a little freaky. My son is 4 yrs old and I have another boy who is 2 yrs old...they ask the odd question and the 4 yr old questioned how I have a baby in my stomach (Im 5 months pregnant) and I told him when mommy and daddy love each other than God puts a baby in the mommy's tummy. He didn't question that and I thought it was good enough. From time to time I get silly questions from the little guy and no longer change in front of him. He has now learned to say which I don't know where he got it 'I love boobies' whenever he sees me changing and questions why I don't have 'balls'. Again I say something surrounded by God because we like to talk about religion so I tell them 'God gives them to boys only and mommy's have boobies' Again they are young enough to accept those answers
