Question
Babies have been experiencing crying within about three hours after being put to sleep since they were two and a half months old. They are normal when awake and fall asleep again after about two hours. They can sleep soundly through the night once they are actually asleep.
Answer
The crying in babies may be caused by calcium deficiency. It is generally recommended to supplement calcium from the first month until the baby is 2-3 years old, especially for those with insufficient sunlight exposure or those on artificial feeding. Three months ago, the baby was mainly supplemented with cod liver oil, while the mother supplemented with calcium. It is suggested that children take Icodextrin and mothers take Calcichew D. After three months, babies can also be appropriately supplemented with calcium and cod liver oil, but not in excess. Babies aged 1-6 months should receive 200 milligrams of calcium and 400 IU of vitamin D daily; babies aged 7-12 months should receive 300 milligrams of calcium and 400 IU of vitamin D daily.
