Parenting your Preschooler from 3 to 5 Years

Between ages three and five, children are learning to navigate the world with more independence. Preschoolers are curious, active and full of ideas, but their brains are still developing. They live very much in the moment and rely on caregivers to help guide behaviour, build skills and stay safe.

You do not need to get everything right. Providing a safe, supportive environment, setting reasonable limits and responding with patience helps children build confidence, resilience and healthy habits.

Use this page to learn what to expect and find age-based checklists to support your child’s development, health and well-being.

Parenting information by age

Parenting from ages 3-4 years

What to expect

At ages three and four, children are curious, active and eager to explore making parenting a preschooler is a hands-on activity! They are learning how to manage emotions, follow rules and interact with others, but their brains do not yet work like adult or older children’s brains. Preschoolers often focus on what is happening right now and may have difficulty remembering rules in the moment.

Because of this, gaining cooperation and setting limits can be challenging. Children may resist at first, but clear, reasonable and consistent limits help create a predictable environment where they feel safe.

This is also an important time to begin building resilience—the ability to cope with challenges, recover from setbacks and keep trying. Everyday experiences, supportive relationships and encouragement help children develop confidence and self-control. Check out Wellington County's ResilienC Newsletter for helpful information.

Your checklist for 3 to 4 years

✓ Book an eye examination before your child starts kindergarten.

  • About one in six children has a vision concern. Eye exams are free and covered by OHIP.

✓ If your child can spit, begin using a small (pea size) amount of toothpaste with fluoride when brushing.

✓ Plan plenty of active playtime with your child, especially outdoor play.

✓ Be an active role model by moving and playing together.

✓ If your child is participating in a sport that recommends a mouthguard, choose one that suits the activity and your budget.

✓ Continue to limit screen time to less than one hour per day until age four.

✓ Once a month, lift your child's lips and check the teeth for any changes such as white lines or brown spots. Contact a dentist if you notice concerns.

Parenting from ages 4-5 years

What to expect

Between ages four and five, children continue to build physical skills, confidence and independence. Active play helps support strong bones, muscles and brain development. As children become more active and begin organized sports or group activities, minor injuries are common.

One injury to be aware of is concussion, a type of brain injury caused by a bump or blow to the head. Concussions can happen even when children are wearing protective gear. Signs may include headache, confusion, dizziness, seeing stars or unusual sleepiness.

If your child may have a concussion, they should stop playing right away, rest and see a doctor the same day. Proper care helps prevent long-term problems.

Your checklist for 4 to 5 years

During this stag, try to:

Limit screen time to no more than two hours per day (less is better).

✓ Support at least 60 minutes of moderate to vigorous physical activity each day.

✓ Encourage healthy sleep habits, aiming for 10 to 12 hours of sleep each night.

✓ Continue helping your child build resilience – the skills that will help them deal with life’s twists and turns.

✓ Book an appointment for your child’s next set of immunizations between their fourth and sixth birthdays.

  • Record these on the yellow immunization record card and report them to Public Health. An up-to-date record will be needed when they start school.

Where to find local programs

Community programs and outings with your preschooler can support their learning, social skills and physical activity. They also give parents and caregivers a chance to connect, share experiences and build support.

When to get help

Contact your child’s healthcare provider or a public health nurse if you are worried about:

  • Feeding and growth

  • Sleep that is not improving

  • Crying that is hard to soothe

  • Developmental milestones (such as movement, speech or social skills)

  • Behaviour that feels hard to manage

  • Your own mood or mental health during pregnancy or after birth

You know your child best. If something does not feel right, it is okay to ask for help.
