How common.is it, for.infants to get tic/twitching? what s the percentage from growing out of it. bc shes a baby is her chance higher to get over it

Quite common: There are many reasons for babies to have twitching or shaking movements. The common and benign startle response may look like twitching to many in the first couple of months, even in their sleep or with a slight if sound. It would be helpful to make a video and share with your pediatrician on your next visit to see if it requires any work up.
