Sleep in 1900: Folk practice

Before the note home, pick only what happened today in Sleep. Year 1900, line “Folk practice,” figure 91. Another household’s pace is not your quantity. Self-report and WEIRD samples bias some literatures — global gaps noted in reviews.

Scores on this page rank evidence strength, daily-life impact, difficulty, age span, expert consensus, and urgency relative to other parenting topics in the atlas. Research from Bowlby, Baumrind, Montessori, WHO, and UNICEF informs the sections below — always interpreted as educational context, not individual medical advice.

Circadian development, night waking, and safe sleep environments — framed by circadian development and safe sleep. Evidence score 91/100 reflects published cohort, RCT, and meta-analytic work — gaps remain in cross-cultural replication. Age range 0–18 years marks peak relevance; principles may extend but intensity varies by developmental stage.

Difficulty score 70/100 captures typical caregiver load — context, support, and temperament modify real experience. Consensus score 75/100 — areas of agreement and live debate appear in the science section. Urgency 88/100 reflects time-sensitivity; some topics tolerate gradual change, others need early action.

The note keeps 1900, “Folk practice,” and 91. It is not a diagnosis of Sleep.1900
