WeiMeiJiao Warm, firm discipline from birth to age 12

Discipline by age

Discipline means teaching, and how you teach changes as your child grows. Choose your child’s age to see what to expect and what to do.

A family walks along a park path: one parent carries two babies, the other holds a toddler’s hand, and two older children walk between them.

The five stages

  • A parent holds a baby face to face in a soft-lit room; the baby smiles and reaches toward the parent.
    0-12 months

    Babies (0-12 months)

    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 (1-3 years)

    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 (3-5 years)

    This is the age for the whole approach: make the rules clear, notice when things go well, and keep consequences calm and brief.

  • In the morning, a child with a backpack heads for the front door while a parent kneels beside them holding a book.
    5-7 years

    Starting school (5-7 years)

    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.

  • Two children water potted plants on a sunny balcony beside a line of drying laundry.
    7-10 years

    School age (7-10 years)

    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.

  • 10-12 years

    Preteens (10-12 years)

    Puberty may be starting, friends matter more than ever, and your child wants a say in the rules. Discipline now runs on trust: fewer orders, more negotiation, clear limits that still hold, and a relationship your child wants to confide in.

Ages are a guide, not a deadline

Children move through these phases at their own pace, and the phases overlap. A 3-year-old can act like a toddler in the morning and like a preschooler by lunch. Even the milestone checklists for well-child visits list what most children (75% or more) are expected to do by a given age, which means some children will get there later.109

So start with the page for your child’s age, and read the one before or after it if that fits better. If you are not sure, the 10-question age finder suggests a phase based on what your child does now. If something about your child’s development worries you, talk to your pediatrician.

How to use these pages

Each phase page opens with a short “Start here” list for when you need something right now. Then come four sections: what’s normal at this age, what works and why, what backfires, and things you can say, with scripts written for that age. Each phase also has a one-page summary you can print and put on the fridge.

The method underneath all six phases is the same: warm attention for the behavior you want, clear instructions, ignoring minor misbehavior, brief and calm consequences, and steady follow-through. It is explained once, with its evidence, in the core of the best-proven approach. The phase pages show how it changes shape as your child grows, from redirecting a baby to holding family meetings with a 9-year-old.

If your child is older than you would like, you have not missed your chance. Two meta-analyses of parenting program trials found no evidence that starting earlier in childhood made the programs work better for disruptive behavior.9
