Patient's question:
NoDoctor's answer:
When an infant is sleeping, if there is a loud noise, the baby often contracts both arms and legs simultaneously or experiences rapid trembling of limbs, showing a "startle" reflex. Sometimes, they may even cry loudly. Don't worry! This is a specific unconditional reflex unique to infants and is a normal phenomenon. You can also try taking Bao Long Wan for children to see if it helps.
