Sources

Last updated 6 October 2026

Nexus researches each guide from the public sources below. This page lists where the information comes from. Some sources are general, and some are community discussion. Community sources show common problems. Health and safety guidance sets the baseline.

Search and public information

• Google Search: search results and common parent questions
• Google Scholar: peer-reviewed sleep research
• PubMed (US National Library of Medicine): medical research abstracts
• Wikipedia: overviews with cited references

Community and parent discussion

• Reddit: public parent discussions and common problems in sleep communities

Health and safety guidance

• American Academy of Pediatrics (AAP): safe-sleep recommendations, healthychildren.org
• NHS (UK): infant sleep and safe sleep guidance
• CDC (US): safe sleep for babies
• Mayo Clinic: infant sleep information
• Canadian Paediatric Society: sleep and safe sleep guidance

How we use these

We use the sources to find common problems, compare what different sources say, and check safety guidance. Where sources disagree, the guide follows the health guidance above. Medical content is general information, not medical advice. Always follow your own doctor or paediatrician.
