I am preparing my DDs for birth because I am known to have fast births. I wouldnt mind having them there. We have been watching You tube videos that are around 10 minutes and DD1 know knows that a baby does not come from a belly button She is not scared by the videos and I think she will cope fine with it. I am also looking into getting a wading pool to have in the family room so that when the time comes, I can be in deep enough water to cover my belly if things do happen too fast to get to the birth centre.
