It is recommended that newborns be burped 2~3 minutes after feeding. Newborns have a small stomach and the anatomical position of the stomach is horizontal, so they may swallow a lot of air after breastfeeding, resulting in overflow, spitting up, or even choking, so newborns should take a break of 2-3 minutes after breastfeeding to burp to help dislodge the excess air. Mothers can sit and hold their newborns with their heads on their shoulders and keep them in an upright position with their faces to their mothers, and gently pat their backs from bottom to top after feeding. The duration of each burp also depends on the situation, some newborns may burp after a few pats, while some newborns are more eager to eat milk and may swallow too much air, so it takes a little longer to burp a few times. If your baby has milk spillage, spitting up or other discomforts, it is recommended to consult a doctor as soon as possible for a clear diagnosis and targeted treatment.
