Evidence-based research on babies, families, and the technology they use. Every finding is backed by sources you can explore and verify.
No study has tested whether logging a baby's feeds, sleep and diapers, by itself, makes parents calmer or more anxious. An evidence review of tracking intensity, comparison with norms and what health authorities ask parents to count.
This review found no published accuracy figure or independent test for the sleep predictions of the baby tracking apps and devices it examined. We look at what infant sleep science, sleep trials and parents' experience say about forecasting a baby's next sleep.
All 14 baby tracking apps examined in a 2026 code audit contained third-party data-sharing mechanisms. An evidence review of privacy practices, security incidents, and legal protections.
