When a baby struggles to feed, one of the most useful questions we can ask isn't about the latch. It's "Tell me about the birth."
Birth is a physical event for the baby, not only for the parent. The forces, positions, and interventions of labor and delivery leave an imprint on a baby's body, and that imprint often shows up first in feeding.
What to ask about
A thorough birth history goes beyond "vaginal or cesarean." Useful details include:
Length of labor and pushing. A very long second stage or a very fast one can both be hard on a baby's head and neck.
Fetal position. Posterior or asynclitic positioning, breech presentation, or a baby who was "stuck" can create asymmetries.
Instrumental delivery. Vacuum or forceps assistance can affect the cranial base, jaw, and nearby nerves.
Cesarean birth. Whether it was planned or happened after labor, and how the baby was delivered through the incision.
Medications. Labor medications can affect a baby's alertness and early feeding behavior.
The first hours. Was there skin-to-skin contact? Separation for NICU care? Suctioning or resuscitation?
None of these guarantee a feeding problem. They give us a map of where to look.
How it shows up
Birth history often appears in feeding as:
A strong preference for turning the head to one side, and difficulty feeding on the other
Facial or jaw asymmetry, or a head shape that's flattened or molded
A baby who seems uncomfortable lying on their back or being handled in certain ways
Tension through the neck, shoulders, or jaw that limits opening
A baby who is sleepy, disorganized, or hard to wake for feeds in the first days
Some of this resolves on its own as the baby moves and recovers. Some of it doesn't, and those babies may compensate quietly until feeding becomes painful or inefficient.
The parent's birth matters too
The lactating parent's birth experience shapes feeding as well. Significant blood loss, a cesarean recovery, a difficult or frightening birth, or separation from the baby can all affect milk coming in, positioning options, and how the parent experiences feeding.
A trauma-informed approach means asking about birth with care. We're gathering clinical information, and we may also be the first person who has asked the parent to tell their story.
Putting it together
Birth history doesn't give us a diagnosis. It gives us context. When we see a baby who keeps the head turned right, can't open wide, and was born after three hours of pushing with a vacuum assist, the pieces start to fit together.
In Functional Lactation, birth history is one of the first things we look at, because the story of the feed often starts there.
