Hello, This is usually a normal finding in newborns and tends to resolve on its own with time. It is called benign neonatal sleep myoclonus, where babies have brief jerky movements only while they are asleep and are completely normal when awake. It becomes a matter of concern if these jerky movements also occur while the baby is awake, are associated with rolling of the eyes, abnormal stiffening or repeated movements of the arms and legs, poor feeding, breathing difficulty, or if the baby appears unusually drowsy. In such cases, kindly consult your paediatrician for further evaluation. If the jerky movements occur only during sleep and stop when the baby is awakened, there is usually no need to worry.

Hi These are normal.

Consult with Pediatrician physically for further evaluation and treatment

Its normal.

Greetings symptoms resemble benign neonatal sleep myoclonus, a harmless, self-limiting condition, but they could also share characteristics with infantile spasms, neonatal seizures, or hyperekplexia. To manage this, parents can take three helpful steps: record a clear video of the jerks, note whether the movements stop instantly upon waking the infant, and double-check any feeding or medication logs. If evaluated by a doctor, standard care options typically involve a thorough physical examination, a routine or video EEG to monitor brain waves, and lifestyle reassurance without medication if the results are normal.

These jerks normal only they are called jitteriness

At 12 days of age, brief jerky movements that occur only during sleep and stop when the baby wakes or is gently touched are often due to benign neonatal sleep myoclonus, which is a normal condition and usually resolves on its own over the next few months. However, if the jerks also occur while the baby is awake, are prolonged, involve eye rolling, lip smacking, breathing difficulty, poor feeding, fever, or the baby becomes unresponsive, the baby should be evaluated immediately by a pediatrician or at the nearest hospital to rule out seizures. If possible, record a video of the episodes and show it to your pediatrician during the visit.
