Ohhh yes!!! It definate plus to drink something with lots of sugar before an ultrasound appt. Not a lot though b/c your tinkle will have high amounts of sugar suggesting gestational diabetes and we don't want that!! You can even drink a couple slurps of coke...
I went with a friend to get her ultrasound and the baby was asleep and not really waking up with bouncing on the belly(with the ultrasound monitor) and the nurse practicioner came back with a dixie cup of coke! Sure enough..About 5 minutes later that baby was exposing himself like never before!!!
So yes..I've heard of that procedure just be careful on the amount you take in!!!
Good luck!!
