I have an ultrasound scheduled for Thursday to (maybe) find out if I'm having a girl or a boy. (I'm 22 weeks) My brother and sister-in-law told me that their doctor told them to drink a Mountian Dew or some other really caffienated beverage before the scan to wake the baby up and get it moving around so I'd have a better chance of finding out. Has anyone eles's doctor ever told them this? Does this actually work? I've pretty much avoided caffiene all together since I found out I was pregnant. Any other hints to get the baby moving?
