What can be done if the baby doesn't sleep well and spits up?

Patient's question:

Doctor; Baby is 56 days old;; Sleeps poorly;; Wakes up once every hour;; Except for vomiting;; Is it necessary to supplement calcium now;;; Thank you. Past treatment history and effectiveness: No treatment, what kind of help is needed: What's going on, what should I do

Doctor's answer:

The baby's stomach is horizontal, and the lower esophageal sphincter above the stomach is not yet fully developed. After feeding, it is easy for milk to reflux, causing spitting up or choking. Additionally, newborns should start taking calcium supplements around two weeks old.
Advice: After feeding, hold the baby upright and gently pat their back from bottom to top to help them burp several times. When lying down, place the baby in a side-lying position to reduce the likelihood of further spitting up. You can start giving the baby calcium and cod liver oil now.
The above advice is for the question "Baby is restless at night and spitting up." I hope it helps. Wishing you good health!
