Patient's question:
When the baby kicks and cries with force, the legs shake like trembling.Doctor's answer:
This is the startle reflex, which every baby has. This reflex is most pronounced in the first three months after birth and disappears completely by six months. The absence of this reflex during the neonatal period indicates brain damage; if one upper limb lacks the startle reflex, it suggests palsy or clavicle fracture of the brachial plexus due to birth injury or other factors. When there is brain damage or acute illness, the startle reflex may be delayed or disappear. If it can still be elicited after four months, it should be noted, and if it persists after nine months, it is a characteristic of chronic brain disease.Recommendation: When she sleeps, if you stay nearby and hold her hand, it will be fine. When the startle reflex occurs, pressing any part of her body can eliminate it. If you sleep next to her, you will find her sleep quality improves. My baby is still like this at four months.
