Question
A 4-month-old baby cries and fusses at night and during the day, and has difficulty staying in bed. They also tend to vomit while eating porridge.
Answer
Based on the age and symptoms, the possible cause is an increased nervous sensitivity due to a calcium deficiency. It is suggested to check for trace elements. Oral supplements of calcium gluconate and zinc gluconate can be taken. Additionally, more outdoor activities can also help improve the situation.
