Sleep science is the foundation of this category. These articles summarize public guidance and research from organizations such as the American Academy of Pediatrics, the National Sleep Foundation, and university sleep labs. You'll find plain-language explanations of baby sleep architecture, circadian rhythms, regressions, and wake windows. Sources are linked in the articles so you can check them directly.
