What the research says
The studies behind the course, explained without the hype: what was measured, in whom, how strong the finding is, and what it means for a parent of a five-year-old. And open data, charted, with the numbers you can download.
We say what a study does not show, not only what it does. Some famous findings are weaker than their reputation — we'd rather you knew.
Data, charted
About 1 in 20 kids aged 5–11 seem very worried every day
About 1 in 20 US children aged 5–11 seem very anxious, nervous or worried every day, according to CDC survey data — and the share has barely moved since 2019. Chart, table and CSV.
About 1 in 6 young children don't usually bounce back quickly when things go wrong
83% of US children aged 6 months to 5 years usually bounce back quickly when things don't go their way — the lowest of four signs of flourishing in the National Survey of Children's Health 2023–2024.
“Calm down corner” went from unknown to a back-to-school staple
US Google searches for "calm down corner" rose from almost nothing in 2016 to a steady yearly pattern, with a back-to-school spike every August. Chart, table and CSV.
Across 60 countries, about 3 in 4 young children are on track socially and emotionally
Across 60 countries, a median 76.5% of children aged 3–4 are developmentally on track in the social-emotional domain, according to UNICEF's Early Childhood Development Index — with a range from 42% to 97%.
Study briefs
Self-control at four: what it predicts, and what it doesn't
Self-control in childhood really does matter for later life — but a single waiting test at age four tells you much less than its fame suggests. The skill is built across years, and it can be practiced.
Coaching feelings, not just stopping them
How parents respond to a child's feelings matters. Children whose parents name and talk through emotions tend to regulate themselves better, and a short parenting course that teaches this reduced behavior problems in a randomized trial.
Small brave steps: what helps anxious young children
For young children with real anxiety, approaches built on gradual, step-by-step brave practice — with parents closely involved — help most of them. Even a brief course for parents of shy preschoolers reduced later anxiety disorders.
Praise and growth mindset: what holds up
How you praise does shape how children handle failure — praise for being clever made children avoid challenges. But the big claims for growth-mindset programs are much weaker than their reputation: on average, their effect on achievement is tiny.
Naming feelings: what the research supports
Children who understand and name emotions better tend to get on better with others and have somewhat fewer behavior problems — a consistent but modest link. The popular "name it to tame it" idea comes from a study in adults.
Screens and behavior: a small link, and new advice
More screen time goes with slightly more behavior problems — a real but small link that doesn't prove screens cause them. Pediatricians now focus less on hour limits and more on what screens displace, such as sleep and play.
The course puts these findings into practice: 24 twenty-minute lessons with your child, one key phrase a week, and a three-minute daily app.
