What should I do if my child doesn't sleep well and always cries?

Patient's question:

My son is one and a half years old. Recently, he hasn't slept well at night, tossing and turning, accompanied by low crying. He keeps kicking the blanket, and the situation repeats all night long. Sometimes he doesn't sleep at all. However, there are no such symptoms during daytime naps. Please advise the experts. Thank you.

Doctor's answer:

The reasons and countermeasures for babies not sleeping soundly and crying
1. Lack of trace elements, leading to decreased blood calcium, which increases the excitability of the brain and vegetative nervous system, causing babies to be restless at night. Calcium and vitamin D need to be supplemented.
2. Too hot or too cold.
3. Accumulated food, poor digestion, heatstroke, or overeating at night can also cause sleeplessness. It is recommended that solid foods like porridge or noodles should be fed at least two to three hours before bedtime, and a little milk should be given again before sleeping.
4. If the baby cries, do not react immediately. Wait a few minutes, as most children naturally fall back asleep within a few minutes after waking up at night.
