What does Benign sleep myoclonus mean?

Benign sleep myoclonus meaning in Medical Dictionary

a unique disorder of sleep in infancy described as rhythmic myoclonic jerks (unexpected muscle mass contractions) which occur if the son or daughter is asleep and which end if the child is awakened. Rest myoclonus usually disappears after a few weeks, more often than not by three months old, given that sleep habits mature. Harmless rest myoclonus might be recognised incorrectly as epilepsy.
