For the newborn baby, there will be a variety of different phenomena from adults, new parents inevitably overwhelmed, the heart of the seventh. But the following kinds of newborn seemingly abnormal situation is actually a normal phenomenon. 1. weight loss Newborn babies lose weight a week after birth, because the baby has been soaking in the mother’s body amniotic fluid (100% humidity), plus the baby eating has not been on the track, the daily discharge of urine and feces, breathing and skin discharge of water invisible to the naked eye, so that the body water loss, resulting in weight loss within a week of birth. The weight loss can reach up to 10% of the birth weight. As the baby gradually adapts, by the 10th day, the weight will increase. If the weight does not increase or even decreases after 10 days, it may be due to improper feeding or affected by disease. 2. Spitting up The pancreatic muscles of babies who are less than 3 months old are not yet well developed, and the stomach capacity of newborns is small, so most babies will slowly spill more or less white milk from the corners of their mouths after feeding, crying and moving around or patting their backs. Therefore, after feeding, family members can pat the baby’s back for a few minutes to avoid excessive crying. As the baby grows older, the spitting up symptoms will gradually ease. However, if the milk is ejected, spit up in large amounts, or spit up with a yellow-green substance, further examination is needed. 3. Swelling of the head The head of a newborn baby delivered vaginally is usually oval-shaped, like a swollen bun. This is caused by the pressure on the fetal head in the birth canal during delivery. Some babies have soft lumps on the head after birth, which are scalp edema or hematoma caused by pressure during delivery and usually disappear 6 to 10 weeks after birth. However, if the lump increases progressively or does not disappear after 10 weeks, seek medical attention. Newborns often grow milky white particles with smooth surfaces near the gingival margin or the midline of the palate, ranging in number from 1 to dozens. These granules are clinically called epithelial beads, commonly known as horse teeth, and are the most primitive tissue for tooth development, formed by the thickening of oral mucosal epithelial cells at 6 weeks of embryonic development. Generally about 2 weeks can be self-absorption, can not be picked with a needle or wipe with a cloth, so as not to damage the mucosa and cause infection. 5. cross-eye Generally speaking, the newborn’s early eye is not yet fixed, looks a little cross-eyed, and eye muscles are poorly adjusted, often with transient squint, is a normal physiological phenomenon, especially in the broad face, flat nose baby. Parents should always hold the baby to look at various places indoors or outside to promote the baby’s eyes constantly turn to prevent crossed eyes. However, if the baby is still cross-eyed at the age of 1 year or older, he or she needs to go to the hospital for an eye examination.
