The first physical examination of a newborn is at birth and the second is usually on the 28th day after birth. The 2 routine checkups for newborns after birth include general checkups, checkups for systemic diseases, and growth and development. 1. At birth: When a newborn is born, the doctor needs to check the skin color, heart rate, muscle tone, respiratory rate, and response to stimulation of each part of the body. At the same time, it is also necessary to measure the newborn’s weight, length, head circumference, chest circumference, and to observe whether there is any cyanosis, cleft lip, and other phenomena. 2. 28 days after birth: This time is usually to check whether the newborn has any systemic diseases, and it is necessary to check the five senses, the abdomen, the navel, the chest, the buttocks, as well as how the growth and development of the fetus is. It is also necessary to look at the closure of the chimney, the genitals, and the anus of the newborn. A newborn checkup is essential for the growth stage and is a more objective reflection of the newborn’s growth and development. If your newborn is crying, refusing to breastfeed, etc., it is recommended that you go to the hospital to find out the cause of the problem and follow the doctor’s instructions.
