Why Do Babies Shake Their Hands and Feet Vigorously?

Question

My baby is three and a half months old. After coughing and returning from the hospital yesterday, she has been experiencing a severe startle reflex while sleeping. She wakes up every ten minutes or so, with her hands and feet shaking vigorously. What’s going on?

Answer

The baby is three and a half months old. After coughing and returning from the hospital yesterday, she has been experiencing a severe startle reflex while sleeping, with her hands and feet shaking vigorously. It is normal for babies to have a startle reflex. If there has been some improvement since returning from the hospital, it might be due to a bit of over-excitement during the treatment process. Gently massaging the baby’s body can help increase their sense of security, or you can wrap her in a small blanket and hold her. If the situation does not improve, it’s best to consult a doctor at the hospital to find out the cause and receive early treatment.
