Physiological jaundice is a manifestation of neonatal metabolic dysfunction, which is temporary and usually appears 1 week after birth. When suffering from physiological jaundice, the newborn has no discomfort in other aspects, eats and sleeps normally, and can recover without medication, which is harmless to the health of the newborn and does not need to worry.
Small fist
For newborn babies, the strength of flexors is stronger than that of extensors, so the baby's fist is always clenched. When the baby is about three or four months old, with the gradual development and maturity of the nervous system, the strength of flexors will gradually weaken, and the strength of extensors will gradually increase, and the two will gradually reach a relatively balanced state.
become weightless
2~4 days after birth, the newborn's weight may not increase but decrease. This is because the newborn is discharged with meconium after birth and loses water. At this time, it is normal that mothers have less milk, newborns don't eat much, and their intake is relatively small.
thrush
Newborns usually have white bumps the size of rice grains or mung beans on their gums, which look like newly sprouted small teeth, commonly known as "horse teeth". If the fat layer in the newborn's mouth (medically called buccal fat body) is too developed, there will be a phenomenon that the cheeks protrude into the mouth, commonly known as "mantis mouth". "Horse teeth" and "mantis mouth" are normal physiological phenomena and do not need special treatment.
