There is always a lot of emotion and love for a new baby when you first become a mother. As new mothers, we are inevitably “fussed” when our little ones change a little. But if there are several situations, new mothers can not panic. 1, physiological jaundice: when the baby is born 3 days, the skin will appear yellow, and will gradually aggravate, 7 to 10 days to reach the peak, full-term infants 15 days to recede yellow, premature infants 2 to 4 weeks to recede yellow. In the period of physiological jaundice, if the jaundice is serious, tears yellow, the whites of the eyes (sclera) are also yellow, the palms and feet are yellow, may be pathological jaundice, the need for prompt medical attention! 2, “horse teeth” and “mantis mouth”: in the baby’s mouth palate midline and gingival area The yellow and white rice-sized particles are formed by the accumulation of epithelial cells or mucus gland secretions, commonly known as “horse teeth”. It can fade away naturally after a few weeks. There is a raised fat pad on each side of the cheek, commonly known as the “mantis mouth”, which facilitates sucking of breast milk. Both are normal. The newborn teeth: a few babies born with premature teeth in the lower incisors or other parts, called “newborn teeth”, usually do not need to be extracted. 4, enlarged mammary glands and false menstruation: newborns of both sexes can have enlarged mammary glands 4-7 days after birth, such as beans or walnut size, 2-3 weeks to subside. weeks to subside. This phenomenon is related to the fact that newborns are born with a certain amount of estrogen from the mother’s body. Some babies may even produce some milk from their breasts. Do not squeeze to avoid infection. Some female babies have a small amount of bloody vaginal discharge or a large amount of non-purulent discharge for 5-7 days after birth, which can last for a week. This is due to the sudden interruption of estrogen from the mother. 5, neonatal erythema and corn rash: 1-2 days after birth, in the head, trunk and limbs often appear polymorphic papules of varying sizes, called “neonatal erythema”, 1-2 days after the natural disappearance. It can also be due to the accumulation of sebaceous glands, forming a yellowish-white rash on the tip of the nose, nose and face, called “neonatal corn rash”, which disappears naturally after peeling off the skin.
