charlie, i'd love to see your 4d scans! i always think it's neat when siblings look like each other....DS1 and 2 have a somewhat resemblance, and i know this is gonna sound strange, but I think if we did have a girl, and she looked similiar to ds1, she'd be beautiful, because ds1 is very much a pretty boy look, and ds2 looks much more like a little man.
i find out on friday what im having so im either gonna have a trio of little boys or 2 boys and 1 girl. I'm excited but dreading the scan at once.
My thoughts about swaying are that I think it can work, I don't think its a magic bullet or even close to a guarnatee of gender. I also believe you are meant to have who you are meant to have, so no amount of crazy swaying will change the future if a person is *meant* to have boy/girls or boys and girls, etc. But I am so glad I found out about swaying mostly because I met everyone on here and everyone is so supporitve and lovely, it's really nice having a cozy group like this :)
