What is a key characteristic of a good asymmetric latch?

A key characteristic of a good asymmetric latch is that most of the areola is in the baby's mouth. This feature ensures that the baby can effectively grasp the breast and create a vacuum necessary for successful breastfeeding. When the baby takes a larger portion of the areola into their mouth, it allows for a more effective latch, which improves milk transfer and minimizes discomfort for the breastfeeding mother.

Having a good latch is crucial for both the baby's feeding efficiency and the mother's comfort. An asymmetric latch tends to ensure that the baby is positioned in such a way that they suckle effectively, utilizing their tongue to compress the breast and draw out milk. This position helps to stimulate the mother's milk production and maintains a smooth breastfeeding rhythm.

The other options describe traits that can be associated with less effective latching techniques, which might not support successful breastfeeding as well as an asymmetric latch would.
