Patient's question:
A 3-month-old baby has been shaking their hands a few times while sleeping during the day and at night, then their eyes open and their breathing becomes rapid, looking very distressed. However, when they sleep on their side, everything is fine, and they can sleep for a long time without waking up. What could be the reason for this?Doctor's answer:
When a baby experiences tremors all over their body again while sleeping, it is a normal physiological phenomenon. During the early stages of deep sleep, although most brain cells are in a resting state, some remain active, which often results in trembling in the hands, feet, wrists, eyelids, or other parts of the body. Additionally, when a child is deficient in calcium, the increased excitability of the nervous system may occasionally lead to hand and foot tremors. However, these tremors only occur during deep sleep and are normal when the electroencephalogram (EEG) is normal during recurrence. If a child has frequent tremors after falling asleep and the tremors last for a relatively long time, an EEG should be conducted to rule out the possibility of other diseases.
