The ear canal of normal newborns can secrete a yellow, transparent, odorless, non-purulent secretion called cerumen, commonly known as “oil ear”. Because the nasolacrimal ducts of newborns are narrow and rich in mucosal blood vessels, they are easily blocked. Therefore, lid secretions are not easily discharged from the nasolacrimal duct through the nasal passage, and eye secretions can continue to occur. It is mostly clear or white. This is different from conjunctivitis lacrimal sac, where the inflammatory secretion is purulent and sometimes accompanied by redness, swelling and heat of the conjunctiva. If this is the case, antimicrobial eye drops are needed. The newborn’s stomach is horizontal and the pancreatic sphincter is relatively loose, so spillage can easily occur after a full meal and a change in position. After feeding, hold the baby’s head and neck and pat his back vertically for a few minutes to make the air burp out and then put him to sleep on his right side, and elevate his upper body if necessary. Vomiting is different from overflowing milk, it can be general vomiting or jet vomiting, some of which comes out of the nostrils and the amount is high, so you should pay attention to the side of the face immediately to prevent choking and accidental aspiration. Vomiting may not always occur after eating, but the specific analysis should be based on the way of vomiting, the color and amount of vomit, the time of vomiting, abdominal signs and the stool to distinguish. Generally speaking, if you experience coffee-colored or yellow-green vomit, you should ask your health care professional to check and analyze the content.

This is mainly due to the influence of the mother’s endocrine hormones, which will naturally subside later and does not require special treatment. Do not hand squeeze, easy to avoid bacterial entry caused by inflammation as follows 5, tongue tether It is the free part of the tongue and the bottom of the mouth associated with the organization, the front and back of the tongue, left and right, upward movement to play the role of restraint and flexible change. Some newborns’ tongue ties grow too close to the tip of the tongue, which affects the outward and upward roll of the tongue, and some tongue tips cannot reach the palate or the tongue extends in a “W” shape (tongue tip depression), which needs to be treated by a dentist, such as “cutting the tongue ties” as the elderly usually say. In the past, basic neonatologists can cut, but now the relationship between the practice of medical authority, to the Department of Dentistry to deal with.
