Before delivery, pregnant women are infected with cytomegalovirus and toxoplasmosis virus, which can damage the brain of the fetus, so doctors usually recommend pregnant women to do eugenic five tests, etc. Pre-eclampsia, maternal anemia, diabetes, and increased blood pressure can affect the brain of the fetus; 2. Pregnant women who weigh too much or too little during delivery can also affect the fetus; 3. After delivery, such as jaundice and asphyxia can affect the baby.
