If you have a limited number of ultrasounds during pregnancy but are curious to find out what is the gender of your baby, there are many methods for that. According to the Pregnancy Board, baking soda is the perfect DIY gender prediction test.
You will have to put a little bit of soda in the disposable cup and put a small amount of your urine in it. If it frizzles like a soda pop, then it may be a boy, but if it does not frizzle, then it may be a girl. This test has been used for testing the gender, and 22 out of 31 have been correct, while only 9 were wrong.
This may be a fun method to try out along with some old wives tales for predicting gender.
