Gender Selection

Hi all, I am new to glow. I am the proud mother of two healthy, and very rambunctious boys. My husband and I are hoping to add another to our brood. I'd be grateful no matter if it were a boy or girl so long as he or she are healthy. However, I'm curious if any women out there have tried any methods (ie diet, sex positions, shettles method) to tip the scale in their gender favor? Do you feel like it worked for you?
