Hi welcome to HCMForum. Most probably what you are thinking to be the movement of the leg might be mild fit.
what the baby is getting is the conservative treat ment. The cause of the fits
should be known first. it may be
during birth jaundice
or congenetal defect. I advise you to consult a neonatalogist for diagnosis. you
may need to have CTscan along with other tests for confermation. the dose your doctor suggested is reasonable.
I advise for a quick recovery.
