Question
Why might a two-month-old baby suddenly wake up and cry during sleep, especially before midnight?
Answer
There can be many reasons for a baby to cry out during sleep at night, including colic or a deficiency of trace elements, such as low blood calcium levels which may increase the excitability of the brain and the autonomic nervous system, making it difficult for the baby to settle down. It is recommended to seek medical attention for a detailed examination and to supplement calcium and vitamin D under the guidance of a doctor. It is also advisable to take the baby out in the sun during the day to help replenish calcium.
