How we verify what we publish
Methodology
Who reviews this site
Sleep Training Planner content is reviewed by Sleep Training Planner editorial team before publication. Review means checking every fact against a primary source, not adding an unverified opinion. We do not claim Sleep Training Planner editorial team holds an industry license or certification unless that is separately disclosed with evidence; the authority this page stands on is the verification process below, not a credential.
How data is sourced and maintained
Sleep Training Planner is not a licensing body and has no exam or fee schedule to cite, so the sourcing here works differently than on a credential-prep site. Every method entry in the comparison matrix is attributed to the peer-reviewed sleep research or published approach it descends from, and readiness, safety, and developmental facts are sourced from the American Academy of Pediatrics' consumer guidance. We do not reproduce a branded course's proprietary content.
Every page carries an updated date, and this site's freshness policy
re-verifies published facts every 90 days. A page that
falls out of that window is queued for re-verification, not left to go stale.
The statistics page is this site's own original data study: every figure on it is computed at build time from the site's own method comparison data, never hand-typed.
Last full verification
The newest verified fact on this site is dated . This date is computed from the site's own content, not hardcoded, and moves automatically as pages get re-verified.
