During pregnancy, a woman can rub her belly with light force without affecting the fetus, but she should be careful not to massage her belly too hard. A light touch on the belly can make the fetus feel loved by the external environment, resulting in excitement and fetal movement. Regularly stroking the fetus with light force outside the body is beneficial to the development and growth of the fetus. You can play music or children’s songs to the fetus, which can also stimulate the brain nerves of the fetus, which is conducive to its intellectual development. When a pregnant woman reaches the middle and late stages of pregnancy, the uterus has exceeded the pelvic area and the abdomen of the pregnant woman has gradually become bigger, so if you often massage your belly with your hand or with heavy force, it will easily cause stimulation to the uterus and cause violent contractions and the possibility of preterm delivery. Stimulating the breasts and nipples of women in the middle and late stages of pregnancy can also easily cause contractions.
