Newborns breathe shallow and fast, about 40 times per minute, sometimes with irregular rhythm, mainly abdominal breathing. Without careful observation, you can't see the chest, only the ups and downs of your stomach. Because the respiratory center has not been fully developed in the first few days, sometimes breathing is irregular and even apnea occurs, especially in premature infants. Generally, it gradually becomes regular after 2 ~ 3 days, but the breathing rhythm will accelerate the heart rate when crying or breastfeeding.
The breathing frequency of full-term newborns is shallow and fast. The respiratory rate can reach 60-80 beats/min within 1 hr after birth, 40 beats/min after 1 hr, and 20-40 beats/min after 2 days. The newborn's breathing is abdominal breathing, and there is obvious breathing movement in the abdomen. Therefore, it is not advisable to bind the abdomen too tightly, so as not to affect breathing.
