Has anyone done any of the old wives gender prediction tests? I didn't do any with my first, and I just did the baking soda one with this one. You put 1-2 TBS of baking soda in a plastic cup, and then you pee in another one. When you add your urine to the baking soda if it fizzes it's a boy, if not it's a girl. I did it lol, and it didn't fizz at all. If you've done this, was it correct? I'm driving myself crazy wanting to know if the baby is a girl or boy. I have a 6 year old step son (husband has full custody) I have a 4 year old son, and I want this one to be a girl so bad!!
