If the baby has a low-level lip tie, then the doctor may teach you ways to gently stretch the frenulum with your finger and increase the mobility of the upper lip. You can then adjust the baby’s lip on the nipple for a better latch. Babies with lip tie may find it easier to latch on to a bottle nipple. So, you can feed formula or expressed breast milk through a bottle. Try different bottle nipples to find the one that works best for your baby.
