Question
An 80-day-old baby, who had a trace element check at one month and showed no calcium deficiency, has recently been found to have thinning hair on the back of the head, with no new hair growth. The baby also has trouble sleeping, often waking up frequently during the day and for short periods during naps, sometimes crying suddenly. The baby’s hand movements can also wake themselves up during sleep, and focusing on sleep does not improve the situation.
Answer
Based on your description, the baby is showing signs of nuchal alopecia along with symptoms of calcium deficiency and easy wakefulness. It is recommended to continue administering Vitamin AD to the baby and taking the baby out in the sunlight on sunny days to promote calcium absorption. If the baby is breastfed, the mother can also consider taking calcium supplements.
