Question
After one month, the baby coughs two or three times every morning and one or two times during the day, with one or two coughs each time. The baby has had a cold twice, each lasting two or three days. Breast milk was discontinued after one month. The baby still occasionally coughs and is unable to lift its head when lying on the stomach. I am worried about whether there might be a brain problem, or if this is a normal developmental phenomenon?
Answer
A four-month-old baby should be able to try lifting its chest while lying on its stomach, but being unable to lift its head is an abnormal sign. This condition may be related to calcium deficiency or other diseases, and it is recommended to take the child to the hospital for a check-up. It is appropriate to get some sun exposure and supplement with cod liver oil for proper adjustment.
