Why does a baby over 1 year old keep humming even while sleeping?

Patient's question:

No

Doctor's answer:

This is a normal phenomenon, which is a physiological response in newborns and almost every child will experience it. The nervous system of a newborn is not yet fully developed, but it will gradually improve around the age of three months. However, if it persists afterward and is accompanied by crying, it may indicate a calcium deficiency. In such cases, calcium supplements can be given to the baby after three months.
