How we build Lunio's sleep guidance
Lunio's age schedules, wake-window ranges, regression timelines, and bedtime advice are built from published paediatric sleep research and consensus guidelines — not personal opinion. This page explains where our numbers come from, who reviews the content, and how we keep it up to date.
Scope
Our guidance covers healthy children aged six months through eight years. We do not provide medical advice, and we do not address clinical sleep disorders, breathing-related conditions, or atypical development. Parents of children with diagnosed conditions or persistent concerns should consult a paediatrician.
Primary sources
Sleep-duration ranges for each age band are taken from the American Academy of Sleep Medicine (AASM) consensus statement (Paruthi et al., 2016), endorsed by the American Academy of Pediatrics, and cross-checked against the National Sleep Foundation expert panel (Hirshkowitz et al., 2015). Wake-window and nap-count patterns are informed by systematic reviews of normative infant and toddler sleep (Galland et al., 2012). Bedtime-routine recommendations draw on the Mindell & Williamson (2018) review of consistent bedtime routines.
Review process
Every age profile and regression page is drafted from the primary sources above, then read end-to-end by a second contributor against the cited ranges before it ships. Numerical ranges in tables must match the cited source exactly; narrative copy must stay within the bounds the source defines. When two sources disagree, we use the AASM consensus.
Update cadence
We re-check the primary guidelines once per year and any time a new consensus statement is published. Last-reviewed dates appear on this page and on age and regression pages.
Not medical advice
Lunio is an educational product. It is not a substitute for diagnosis or treatment by a qualified clinician. If you are worried about your child's sleep, breathing, or development, please speak to your paediatrician or family doctor.
