Introduction: During pregnancy, pregnant mothers will have many bad habits, and these bad habits will affect the healthy development of the fetus. Therefore, pregnant mothers should exercise more during pregnancy and pay attention to dietary taboos during pregnancy, so that they can give birth to a healthy and well-behaved baby. Recently, a study published in the new issue of \”Pediatrics\” pointed out that parents should intervene early during pregnancy to cultivate their baby\’s sense of taste. Expectant fathers and pregnant mothers should not think that their words and deeds will not affect the fetus until the baby is born. In fact, your bad habits can also be transmitted to your fetus.
