Pre-1900
Folk practice
Preschool guidance lived in proverb, religion, and midwifery before academic child study.
Preschool history tracks shifting expert authority — from religious manuals through behaviourism to attachment and neuroscience frames.
Each era reinterpreted play-based learning and social entry through available science and cultural values about children, gender, and state responsibility.
Where it began
1917Geneva
Preschool entered formal childcare discourse around 1917 as psychology, paediatrics, and education institutions professionalised family life.

The eras
1900–1950
Professionalisation
Universities and clinics began publishing age-stage norms and hygiene rules.
1950–1980
Attachment turn
Bowlby, Ainsworth, and Baumrind reshaped how closeness and limits were discussed.
1980–2010
Brain and policy
Neuroscience metaphors and international ECD programmes entered parenting culture.
2010–present
Digital parenting
Social media accelerates method wars; evidence reviews struggle to keep pace.
Practices that changed
Approaches that faded, flipped or were replaced as evidence and culture moved on.
Punitive to relational
1960s–2000sHarsh control models faded as play-based learning and social entry research linked warmth with better outcomes.
Expert to co-regulation
2000s–2020sParents expected to manage their own arousal while teaching children — not just enforce rules.
National to global
1990s–presentWHO and UNICEF standards interact with local kinship systems worldwide.
Today's preschool discourse blends global WHO standards with local kinship practice and algorithmic parenting media.

Newborn
The first 28 days after birth — physiology, bonding, feeding rhythms, and the shift from womb to world.
Evidence 88 🍼Infant
From one month to twelve months — motor milestones, first foods, attachment deepening, and emerging sleep patterns.
Evidence 90 🧸Toddler
Walking, talking, and testing limits — the toddler years blend motor explosion, language bursts, and autonomy struggles.
Evidence 85 📚School Age
Industry, friendships, and academic skill-building mark middle childhood between toddler chaos and adolescent identity work.
Evidence 78 🧑🎓Teenager
Brain remodeling, identity formation, and increasing autonomy define adolescence — risk and capability both rise.
