Just chasing some advice....

I am booked in for my 20 week ultrasound on Thursday and am really excited about hopefully finding out the sex of the baby . However, as DH and I are hoping to keep this little detail to ourselves we are telling everyone that we aren't going to find out, so that they won't ask us!!! And if we slip up and say "he" or "she", if they think we don't know ourselves, they won't think anything of it.

The catch is that my parents are in town visiting at the moment and Mum keeps asking about the scan "when is it?", "where is it?", "will DH be able to go with you?" (i.e., hinting about coming along). Obviously, she can't come or she'll find out the baby's gender too! I also won't be able to show them the video recording as it will include audio of our conversations during the scan.

Any suggestions PLEASE on how to keep my Mum out of my ultrasound without hurting her feelings?? I thought of telling her that it's the policy of the clinic not to allow in anyone other than the partner. Any thoughts????

Thanks heaps.
