I have my 20wk scan in a few weeks, and I was wondering whether to take my 4.5yo ds with us. He knows that there is a baby coming, but I don't think that he's twigged that it is in mummy's tummy! I thought it might be nice for him to share the experience, but I wasn't sure how the staff would be. He is well behaved, and dh will be there to. Anyone else taking children with them?
