Question
My child is 42 days old and has been doing well. There were no abnormalities on the 29th (fed after wiping the breasts with cool water). On the 30th, vomiting occurred, with difficulty in defecation and a decrease in quantity. Stool was normal without any abnormalities. On December 1st, there was no improvement; vomiting was severe, with undigested food and also a curd-like consistency. Stool was normal without any changes, just less in quantity. The child’s mental state is good, they can hold up when uncomfortable, and it’s fine when their head is on my shoulder. I fed them some water on December 1st.

This makes newborns, especially premature infants, prone to vomiting. The most common cause of vomiting in newborns is improper feeding, accounting for about 1/4 of all newborn vomiting cases.

Severe vomiting can cause vomit to be Inhalation into the trachea, leading to aspiration pneumonia and blocking the airways of weak infants and premature babies, causing asphyxiation and death. When a child vomits, parents should first check the feeding method and correct any improper practices promptly. When breastfeeding or feeding water,
