Honestly.. i think youre better off just being honest with them and telling them you dont want anyone else there. You could be in labour for hours (lets hope not!) so them waiting outside, theres no point. Plus youre going to want to rest after you give birth anyways, not see people. Hun i think for your own sake (it is YOU giving birth after all), i would just tell them to please stay away until you call. Last thing you want is a million people sticking their faces in when its not wanted.
