Question
A 6-month-old baby, during both day and night naps, always shakes their hands a few times before opening their eyes and breathing becomes rapid, feeling very uncomfortable. However, if they sleep on their side, there is no problem, and they can sleep for a long time without waking up. What is going on?
Answer
In the initial stages of deep sleep, some brain cells in babies may still be in an excited state, leading to hand, foot, or wrist tremors. Additionally, if the baby is deficient in calcium, the increased excitability of the nervous system may also cause hand tremors. This type of tremor usually only occurs during the deep sleep process and is shown to be normal on an EEG. However, if the child frequently trembles for a prolonged period after falling asleep, it is recommended to undergo an EEG to rule out other diseases.
