Question
The two-month-old baby barely sleeps during the day, falling asleep at 7 PM every night and waking up at 4 AM the next morning. They can only manage to sleep for half an hour at most during the day. I’m worried this might affect their health.
Answer
This is a symptom of vitamin D deficiency, possibly leading to rickets. It is suggested to try taking α-calcitriol for treatment, one tablet per dose, twice a day, for a continuous period of two months.
