Question
A child has been waking up to cry four to five times every night since birth, even after drinking milk, and needs to be comforted for a long time before falling asleep again. This has caused great concern and headache for the parents. After a hospital check-up, it was found that the child was not lacking in nutrients such as calcium and zinc. The child is always very active during the day, playing around everywhere, so I would like to ask the doctor why the child always cries at night?
Answer
The current situation may be due to a lack of vitamin D leading to calcium deficiency, which in turn causes the child’s irritability and sleep problems. It is recommended to supplement vitamin D. Additionally, children do not enter deep sleep indefinitely; the deep sleep cycle is about 40 minutes. After waking up, the child may cry and need to be comforted by an adult, which is normal. If the situation does not improve, it is recommended to seek further treatment from a pediatrician.
