So my husband and I figured we would give it a try. I am currently 10 weeks 2 days. Tablespoon of baking soda in one disposable cup, fresh urine in another. Simple enough. If it fizzes like shaken soda your having a boy, no reaction at all renders a girl. We got lots and lots of fizz!!!!! Fingers crossed, hubby is dying for a baby boy as I already have two boys and he has two girls!!! I'm also hoping for another boy. I'm a spartan woman and only breed boys(hopefully). And yes for the smart asses I am aware that the man determines the sex of the baby I'm not stupid. Has anyone else tried the baking soda gender test with accurate results??? Just curious.
