Question
Why does a baby under one month old keep straining and vomiting every time they strain?
Answer
This is a phenomenon of physiological regurgitation, as the infant’s esophageal muscles have not fully developed. Therefore, vomiting may occur again after feeding due to vigorous movement or coughing. It is recommended to avoid overfeeding during each feeding, gently pat the baby’s back after feeding to help them burp, and be gentle with movements after feeding to reduce the chance of vomiting. Additionally, the baby should be placed in a side-lying position when lying down, and the baby’s head should be lowered quickly during vomiting to prevent milk from entering the lungs.
