Feeding problems are the most common signs of tongue and lip ties. Your child’s lips and tongue need to be able to move properly to latch onto the nipple and stimulate it for proper feeding. If they seem to be having trouble making a proper seal, milk dribbles out from their mouth while feeding, or they frequently stop and start feeding, they may be having latching issues due to tongue or lip ties.
You can also look for visual signs of tongue and lip ties. For the lips, you can fold back your child’s upper lip and look at the frenulum. If it is difficult to lift the lip or it seems like your baby is unable to move their upper lip on their own, they may have a lip tie.
Signs of tongue ties include an inability for your child to stick their tongue out past their front teeth, or problems moving the tongue from side to side. Tongue ties can also be identified visually. A common sign of tongue ties is a “heart-shaped” tongue. When your child sticks their tongue out, the restriction caused by the tongue tie may cause it to look “notched” or heart-shaped, instead of appearing as a smooth “U” shape.
