Today, pregnant mothers can easily know that they are about to welcome the princess or the prince with an ultrasound, but many parents prefer to choose the legendary color method of predicting the sex of their child. Let's take a look at that series of stories and if there is science behind it.
Fact: This perception is considered to be one of the most popular myths of all time. It is believed that if a woman is pregnant with the mother's belly low (or protruding forward) then she is probably pregnant with a son and vice versa. However, science has proven that belly shape has no evidence to determine a baby's sex. In fact, how a mother's belly looks depends largely on the shape of her body, her weight, her muscles and the position of her baby.
Reality is: Although the reality of this story sounds like it's based on some scientific evidence, it's not really accurate. Studies show no gender-related difference in fetal heart rate. From week 30 onwards, the fetal heart rate is likely to slow down. The heart rate cannot say anything but the health of the baby.
The reality is: This is a story that can be passed on by people. Your baby may like sweets or sour foods, but that doesn't say what gender your baby is. If you suddenly change your habits, prefer to eat sweet or sour foods, it's your hormonal change, not the angel in your stomach.
Reality is: According to this legend, a mother much morning sickness is a prediction for a little girl. The hormone responsible for maternal morning sickness is usually higher than in women who are pregnant with girls, whereas if the mother is pregnant with a boy, morning sickness goes better.
Your angel can be a boy or a girl, so the chances in traditional ways like this are only 50/50, like when you play a coin flip. If you really want to know the sex of the fetus to make decisions such as choosing room paint or buying baby clothes early, the only correct way is to go for an ultrasound.
