What is the reason for newborn vomiting milk at 20 days?

Patient's question:

1·15 days / sometimes spits up milk

Doctor's answer:

Hello, as you described, this is generally normal. If it's severe, you need to go to the hospital for further gastric lavage. Additionally, you can take pediatric Domperidone Suspension. After breastfeeding, you should hold the child upright and pat their back to burp. It usually doesn't affect much, so there's no need to worry.
The child is affected by neonatal diseases, so parents must take the child to the hospital immediately for treatment to avoid various misunderstandings. Timely symptomatic treatment is essential. For parents, it's important to observe changes in the child's symptoms and do their best to help the child receive timely treatment for the illness.
