Where every claim here comes from

Every fact in this app and on these pages points at one named page from the American Academy of Pediatrics, the World Health Organization or the NHS. Nothing is published without a source behind it, and each was fetched and read rather than assumed.

Every page cited

Last fetched and read on 2026-08-29. Where a source has since moved, the link points at the page that replaced it rather than at a redirect.

This is general information, not a substitute for your own doctor, midwife or health visitor — they know your baby, and this page does not.
