I know of one gender test that has been pretty reliable for me.. You HAVE to do it outside though as it makes all kinds of ugly smells!
You take the crystal drano (if you can find it) and you pour your pee on it.. if it stays blue its a girl if it turns an ugly brownish color its a boy!
Use 2 T of drano with a few ounces of pee.. and don't forget ONLY outside!
It worked with 3 of my kids! good luck, don't know the baking soda one, but maybe its same idea!
So excited for you Stacey!
Where at 2peas? I live near Vancouver!
Oh yea the drano does stink a lot! I should do my pee and see if it fizzes since I am not pg! lol
