In this condition the bridle beneath the tongue is either too short, or is attached so near the tip of the tongue as to interfere, at first, with the movements of the organ in sucking, and, afterward, in speaking. Although frequently suspected, it in reality occurs very rarely. The best way to determine if tongue-tie exist or not, is to watch whether the infant can protrude the tip of the tongue beyond the lips. If so, it will be able to suck a good nipple readily, and nothing need, nor ought, to be done. Should the reverse condition prevail, it will be necessary to nick the bridle, and, as there is considerable danger of hemorrhage in this operation, a surgeon must always be consulted.
