What are the statistics on reduced stillbirths associated with Hilary Erickson's kick count techniques?

Hilary’s content focuses on how to do kick counts correctly and the fact that they can reduce stillbirths, but it does not quote a specific percentage or exact statistic tied to her personal technique or program.

What is shared in her posts is that:

• Kick counts are believed to prevent about 1 in 4 stillbirths that might otherwise occur
• Some “false alarms” are expected, but considered worth it for those prevented losses
