Quick answers
What defines sleep?
Circadian development, night waking, and safe sleep environments — framed by circadian development and safe sleep.

Age range 0–18 years marks peak relevance; principles may extend but intensity varies by developmental stage.
How hard is sleep in practice?

What do experts agree on?
Consensus score 75/100 — areas of agreement and live debate appear in the science section.
How urgent is attention to sleep?
Urgency 88/100 reflects time-sensitivity; some topics tolerate gradual change, others need early action.

Feeding
Breast, bottle, solids, and picky eating — Ellyn Satter's division of responsibility frames feeding as a relational not battlefield task.
Evidence 93 📱Screen Time
Screens displace sleep, movement, and conversation — WHO, AAP, and UNESCO guidance converges on limits under five with quality over quantity debates.
Evidence 82 🚧Discipline Conflicts
When limits meet resistance — discipline conflicts escalate when stress, inconsistency, or developmental mismatch go unaddressed.
Evidence 79 👯Sibling Rivalry
Competition for attention and resources — Judy Dunn's sibling research shows conflict is normative but manageable with fair attention and teaching repair.
Evidence 76 🎒School Readiness
Self-regulation beats flashcards — school readiness combines executive function, language, and social entry more than early academic drilling.
