If a newborn experiences hand trembling during sleep, what factors might be causing it, and how should it be handled?

A baby may shake during sleep due to a lack of trace elements or low blood calcium levels.

For a newborn baby within five days of birth, shaking during sleep may be due to incomplete development of body temperature regulation or excessively low environmental temperature. It is recommended that parents ensure the room temperature is between 20 to 22 degrees Celsius and use appropriate warming measures. At the same time, the baby may be adjusting to the environment separate from the mother, which could lead to restless behavior.

Explain the difference between fever convulsions and shaking, and discuss possible treatment methods.

Shaking during the fever phase of hand, foot, and mouth disease may be due to low-grade fever, and immediate physical cooling measures should be taken.
