Having studied midwifery for the past 3 years, I have had a lot of questions from my three boys about birth and where the baby comes out etc. I have always decided on the truth with limited details depending on their curiosity. They all know babies can come out vaginas, or via an operation if there is a reason the baby can't be born vaginally. They all know how they were born, how many hours I was in labour etc. Interestingly, none have asked how they got in there yet! (my eldest is 8)
