Question
The 50-day-old baby has been refusing to take naps recently and suddenly cries during nap time, with loud cries that stop when picked up but resume when put down, requiring holding to fall asleep. The baby’s belly is not hard, and bowel movements and urination are normal. The baby is well-warmed at night and has not caught a cold. No treatment has been received, and there are no obvious treatment effects.
Answer
The 50-day-old baby’s refusal to take naps and sudden crying during nap time may be due to calcium deficiency causing difficulty in falling asleep, easy waking, and night terrors. Generally, cod liver oil can be started as a preventive measure for calcium deficiency after one month of birth. It is recommended to undergo a blood calcium test to determine if there is a calcium deficiency. If diagnosed with calcium deficiency, immediate calcium supplementation is needed, along with oral vitamin D supplementation and increased sun exposure to promote calcium absorption. If the symptoms are caused by calcium deficiency, they will disappear after calcium supplementation treatment.
