I've got my 12 week scan next week and just realised won't have childcare for my 2dc (4 and 2). Do you think it's ok to bring them? Haven't told them I'm preg properly, although ds1 has noticed my growing belly so I've warned him there may be a tiny baby in there but we'll need to check at the hospital. He is very excited! My worry is if there is something wrong and they need to talk about serious stuff would be very hard with the kids bouncing round. What would you do?
