Greenfield, Jomeen & Glover: Trauma and Family Size (Frontiers in Psychology, 2019)
Birth trauma cuts family size in half for the majority affected
53% of women with birth trauma are less likely to have more children. Trauma reshapes the entire family.
Greenfield and colleagues published a 2019 study in Frontiers in Psychology examining how birth trauma affects subsequent reproductive decisions. The headline finding: 53 percent of women who reported their first birth as traumatic were less likely to have additional children than they had originally planned.
The team surveyed women several years after the birth, which gave time for the immediate emotional response to settle into a stable pattern. Common reasons given included fear of repeating the trauma, persistent physical symptoms from the first birth, and changes in the woman's sense of what kind of mother she could be. The effect held across different definitions of traumatic and across maternal age groups, which suggests it is not a temporary response to a hard delivery.

Why it matters
Birth trauma does not stop at the delivery. For more than half of affected women, it permanently changes how many children they have. That is a population-level demographic effect, not a personal one.
This is one finding from the research library behind How to Birth a Mother. Everything here traces back to a study, a dataset, or a systematic review.
