The short answer
At 31–36 months, use short, concrete, consistent rules and tell your child what to do instead. A child may understand a rule but still need calm repetition to learn it.

What does setting limits mean at 31–36 months?
A limit teaches which behavior is safe and expected. It is not about frightening or controlling your child.
The AAP recommends showing the behavior you want, setting clear limits, and noticing positive behavior.
How should you state a rule?
Use a short, specific phrase your child can understand, such as “Blocks stay on the floor.”
Tell your child what to do instead: “You can roll the block on the floor.”
How many rules should you start with?
Start with only a few important rules. The CDC says toddlers and preschoolers may learn and remember about two or three rules at a time.
Prioritize safety and daily routines. Add another rule when the first ones become familiar.
Do choices weaken a limit?
No. Offer two acceptable choices within the limit when possible. This supports independence while keeping the boundary clear.
For example: “It’s time to go outside. Do you want the red coat or the blue coat?” The adult keeps the plan; the child chooses between options.
What if your child says no?
Repeat the limit briefly instead of entering a long argument. Understanding a rule does not mean your child can follow it every time.
For safety, give a clear direction without offering a choice: “Hold my hand while we cross.”
Are consequences appropriate?
A calm, related consequence can help a child understand what happens next. Explain it simply and follow through consistently.
If a toy is thrown, put it away briefly and show how to use it safely. The goal is teaching, not revenge or embarrassment.
Why does consistency matter?
Consistent, predictable responses help children know what to expect.
When possible, caregivers should use the same key rules and similar responses.
Should you yell, hit, or shame your child?
No. The AAP advises against physical punishment, yelling, and shaming as discipline strategies.
Stay calm and firm, restate the limit, and show the expected behavior. If you feel close to losing control, make sure your child is safe and take a brief pause.
What can you try today?
Choose two important limits and pair each with a clear replacement behavior: “No hitting; use gentle hands.”
Use the same brief wording throughout the day and notice your child right away when they follow the rule.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Frequent risk of serious harm to self or others during limit-setting.
- Behavior persistently disrupts family or child-care life.
- Other developmental or communication concerns are present.
- A caregiver is struggling to manage anger safely.
