👉 Underseated, also known as a "shallow" or "plump" chest, is a condition in which the breastbone (the soft tissue that forms the inner breastbone) is not fully formed and does not fully expand during pregnancy. This can lead to a lack of support and movement for your baby's head and shoulders. Underseated breasts are often associated with issues such as preterm labor, increased risk of postpartum complications like infections or bleeding, and difficulty breastfeeding.
