Patient's question:
NoDoctor's answer:
When children sleep at night, they are often restless. In fact, during infancy, there is a prolonged period of light sleep, during which infants exhibit various facial expressions such as smiling, frowning, pouting, or making funny faces. Sometimes, their limbs stretch slightly, and they may make sounds like "Hmm-hmm" or have irregular breathing patterns. Therefore, parents may think that their baby's sleeplessness is likely due to light sleep, which is a normal phenomenon.
