Patient's question:
My baby is 31 days old. Recently, he hasn't been eating well and isn't sleeping soundly. Yesterday, he even vomited. What's going on? Is there something wrong with him? I'd like to ask the doctors for an answer. There's no cold or diarrhea recently, just that four days ago, I startled him, and I wonder if that could affect his appetite. The parents are worried. Thank you.First follow-up question: It's spitting up, not vomiting. It goes nearly a meter away. Is there nothing wrong?
Second follow-up question: If there's a head-related issue, what other symptoms would there be? Thank you.
Third follow-up question: Thank you to all the netizens and doctors.
Doctor's answer:
Hello. Infants, due to the underdeveloped function of the cardiac sphincter, are prone to nausea and vomiting under certain stimulating factors, which is related to feeding. Fast feeding, excessive or insufficient feeding volume, frequent changes in milk formula, early introduction of complementary foods, prolonged crying before feeding, swallowing large amounts of air during feeding, not holding the baby upright and burping after feeding, or significant changes in body position after feeding (such as changing diapers) can all cause vomiting.
