"Binkie flutter," an apparently voluntary behavior of infants, possibly related to vibratory jaw movements in dogs: report of 4 cases.
Four cases of apparently voluntary rapid vibratory pacifier movements occurring in normal, unstressed infants up to 1 year of age and captured on video are presented. I speculate on the possible relationship of the movements to similar vibratory jaw movements in dogs, in which species they may represent a neuromuscular mechanism for rapid feedback control.
