During latch-on, a baby's mouth forms a tight seal around the nipple and most of the areola (the dark skin around the nipple). Signs that your baby has a good latch-on include:
- The top and bottom lips are wide open (like a big yawn).
- The lower lip is turned outward against the breast.
- The chin is touching the breast, and the nose is close to the breast.
- The cheeks are full.
- The tongue comes out over the lower lip during latch-on and stays below the areola during nursing.
- You and your baby are completely comfortable during breastfeeding. You may feel some tugging and pressure, but no rubbing of your nipple or pain.
