In order to have the best results with nursing, babies need to create a vacuum type pressure with their lips and tongue on the breast. This aids in the release of milk.
When a baby has a tongue and/or lip tie they compress or squeeze their mother in order to facilitate the release of breast milk. This can be quite painful for mom which leads to a shorter nursing time period and a decrease in all the benefits associated with breast milk.
Thankfully there is a minor surgical procedure that can correct the tongue and/or lip tie. This makes breastfeeding much less painful for mom and allows the child to form a far better latch. This procedure is done in all age groups. As we age a tight frenum can cause difficulty with speech, spacing of teeth, eating and even sleeping.
