A baby over two months old shakes head and moves hands and feet restlessly during sleep.

Under normal circumstances, a baby over two months old shaking their head and moving their arms and legs during sleep may be caused by physiological factors, but pathological factors such as calcium deficiency or colds cannot be ruled out. Treatment should be based on the underlying cause. Specific analysis is as follows:

I. Physiological Factors

If the room temperature where the baby sleeps is too high or if the baby is covered with thick bedding, discomfort may occur, leading to head shaking and restless limb movements. This can be improved by appropriately adjusting the room temperature or reducing the amount of bedding.

II. Pathological Factors

1. Calcium Deficiency

A lack of calcium in the baby's body can affect normal growth and development and lead to restless sleep. Under medical guidance, medications such as calcium carbonate D3 granules, calcium gluconate oral solution, or Longmu Zanggu granules may be administered for treatment.

2. Cold

A cold is a common illness that may cause general discomfort in babies, such as fever and body aches, thereby affecting sleep quality. Under medical guidance, medications such as pediatric paracetamol-phenyl syrup granules, pediatric cold granules, or acetaminophen tablets may be used for treatment.

Besides the above causes, conditions such as acute gastroenteritis, epilepsy, or infantile spasms should also be considered. Medications like smectite powder, live bacillus licheniformis granules, or bifidobacterium combined live bacterial granules may be taken orally. Due to the baby's young age, medication must strictly follow medical instructions—do not adjust dosages without authorization. Seek prompt medical attention if symptoms become severe.
