WeiMeiJiao · Warm, firm discipline from birth to age 10
Disciplining your child, without the guesswork
Free, practical help with discipline from birth to about age 10, built on research. If things are hard right now, start with what to do, and read the why when you have a moment.
Give lots of warm attention to the behavior you want, and meet the behavior you don’t want with clear, brief, consistent limits.
How old is your child?
Children change fast from one stage to the next, and so does what works. Pick a stage to see what’s normal, what works and what to say.
- 0-12 months
Babies
The first year needs no punishment. It needs a grown-up who responds, a few predictable routines, and a home that is safe to explore.
- 1-3 years
Toddlers
Your job at this age is simple to say and hard to do: hold a few firm limits, keep them kind, and help your child calm down when feelings get too big.
- 3-5 years
Preschoolers
This is the age for the whole approach: make the rules clear, notice when things go well, and keep consequences calm and brief.
- 5-7 years
Starting school
Starting school brings long days, new rules and new people, and new questions at home: what to do about a lie, a lost privilege or a fight over what’s fair.
- 7-10 years
School age
This is the age of more homework, more friends and more screens, and more negotiating about all three. Your role shifts from running every minute to coaching, solving problems together and handing over trust step by step.

About this site

The site cites academic sources only: peer-reviewed studies, systematic reviews and meta-analyses, and policy statements that medical and scientific bodies published in journals. Whenever a page says what works, what harms or what is normal at an age, a small number links to the full entry on the Research page. Where findings are mixed or researchers disagree, the page says so. How to read the research.
This is educational information, not medical or psychological advice. If you are worried about your child, see when to get professional help.
