Have never known and loved surprise both times. When had scan for DS1 in waiting room DH was still telling me he wanted to find out but I didn't, in the end radiologist wrote it down in a sealed envelope and gave to me in case DH convinced me to know!! I carried in diary for rest of pregnancy and we opened when DS1 was a few hours old to see if was correct, it was. So msny friends couldn't believe I carried it without wanting to look!

DS2 we also had written down as DH wanted to do same again and see after if right.
