Key Takeaways

Happy second birthday. A 2 year old can usually run, kick a ball, build a tower of four or more blocks, and put two words together, per the Canadian Paediatric Society.
Big personality. Independence, defiance and make-believe all run strong — the heart of the “terrible twos,” which are really just a developing sense of self.
Steady toddler routines. Family foods, iron-rich options, milk capped at about 500 mL a day, and around 11–14 hours of sleep.

Your Child at 2 Years Old

A 24 month old (2 years) can usually run, kick or throw a ball, walk up and down stairs with help, build a tower of four or more blocks, put two words together, and play alongside other children, per the Canadian Paediatric Society. Toddlers eat a variety of family foods, need about 7 mg of iron a day, and take whole cow’s milk or a toddler formula up to about 500 mL a day, from a cup. Total sleep is around 11–14 hours, usually on one nap.

Happy second birthday. Your 2 year old is running, talking in little phrases, playing pretend, and asserting their will with gusto. It’s a big, spirited, endlessly curious stage — the foundation for the preschool years ahead.

This guide covers what’s normal at two: the milestones, toddler feeding, sleep and routines, and the development that’s coming next.

2 Year Old Development: Milestones & Growth

At 24 months, most toddlers reach the set of milestones the Canadian Paediatric Society describes for this age, and begin building toward the next set at 3 years.

Gross Motor

A 2 year old can usually begin to run, kick or throw a ball, climb into and down from chairs without help, and walk up and down stairs with help, per the Canadian Paediatric Society. Over the next year, children build toward running easily, jumping, and walking stairs with alternating feet, which the CPS lists at 3 years.

Fine Motor

A 2 year old can build a tower of four or more blocks, complete a simple shape-matching puzzle, and turn board-book pages easily, per the Canadian Paediatric Society. Offer blocks, puzzles, crayons and lots of hands-on play.

Social & Language

A 2 year old starts to put two words together, copies adults and other children, gets excited about being with other children, plays alongside them, shows increasing independence, and shows defiant behaviour, per the Canadian Paediatric Society. Make-believe play is blossoming. Keep talking, reading and playing together.

Your Life This Month: The Parent Experience

The “terrible twos” are really a developing sense of self — big wants, big feelings, and not yet the words or self-control to manage them. Offer simple choices, keep limits calm and consistent, name feelings, and reconnect after the storms. Your steadiness is what helps most.

Two is also wonderfully fun: conversations, jokes, pretend adventures, and a child who’s more of a companion every day. Lean into the play and the connection.

Parenting a toddler is a lot. If you’re feeling low, anxious or worn down, your doctor or public health nurse can help — please reach out.

What to Do This Month

DEVELOPMENT & PLAY

  • Offer active play — running, ball games, climbing — and safe space to move.
  • Provide blocks, puzzles, crayons and pretend-play props; read together every day.
  • Expand on your child’s phrases, name feelings, and set up chances to play near other children.

FEEDING

  • Offer a variety of family foods in safe textures; keep iron-rich foods coming toward the ~7 mg daily need for 1–3 years.
  • Keep milk (whole cow’s milk or toddler formula) to about 500 mL a day, in a cup — and ask your provider about moving to lower-fat milk from age 2 if you wish.
  • Offer water with meals and snacks; continue vitamin D for breastfed and partly breastfed toddlers.

HEALTH & SAFETY

  • Keep up regular dental visits and brushing teeth twice a day.
  • Supervise near stairs, streets and playground equipment, and keep hazards and choking-risk foods out of reach.

Feeding Your 2 Year Old

At two, your child eats a range of family foods and drinks from a cup. Appetites swing day to day — offer healthy options at regular meals and snacks and let your child decide how much. Iron still matters: toddlers 1 to 3 years need about 7 mg a day, per the Canadian Paediatric Society, so keep iron-rich foods in the rotation, paired with vitamin C.

Keep milk — whole cow’s milk (3.25%) or a toddler formula — to no more than about 500 mL a day, the Canadian Paediatric Society advises, so it doesn’t crowd out food or lead to iron-deficiency anemia. From age 2, many families move to lower-fat cow’s milk; ask your doctor or public health nurse what’s right for your child. Continue a daily 400 IU vitamin D supplement for breastfed and partly breastfed children.

A note on formula this month. Whole cow’s milk or a toddler formula can be your child’s milk at two. If you choose formula, MOF’s organic HiPP Dutch Stage 3 is a toddler formula for 12 months and up, iron-fortified to provide iron, DHA and vitamin D alongside meals. Keep total milk to about 500 mL a day so it doesn’t crowd out iron-rich foods. Go with what works for your family.

Pure formula. Every stage.

Sleep at 2 Years: What’s Normal & How to Help

A 2 year old usually sleeps around 11 to 14 hours over a 24-hour period, per the Canadian Paediatric Society, typically on one afternoon nap. As children approach 3, sleep needs ease slightly (the CPS gives 10 to 13 hours for ages 3 to 5), and the nap may eventually drop — but most 2 year olds still nap.

Keep the bedtime routine consistent, wind down about half an hour before bed with stories or quiet play, keep the room dim and cozy, and be gentle but firm if your child protests. Avoid late-afternoon naps, don’t ignore bedtime fears, and offer a comfort item, which is often important at this age.

Safe sleep reminder: place your child on a firm, flat sleep surface, and follow current local safe-sleep guidance for their age.

When to Contact Your Doctor or Public Health Nurse

Contact your doctor or public health nurse if you notice:

  • A high fever or your child seeming very unwell.
  • Your child is eating very poorly, drinking far less than usual, or isn’t growing as expected.
  • Signs of possible iron deficiency the CPS describes — pale skin, poor appetite, low energy or slow weight gain (too much milk is a common cause).
  • Your child isn’t running or walking, isn’t using any words or two-word phrases, or seems behind in more than one area — the Canadian Paediatric Society advises speaking with your doctor.
  • Your child has lost a skill they previously had.
  • Any concern about your child’s development, feeding or your own wellbeing.

Frequently Asked Questions

What should a 2 year old be doing?

A 2 year old can usually run, kick or throw a ball, walk up and down stairs with help, build a tower of four or more blocks, complete a simple shape puzzle, put two words together, play alongside other children, and enjoy make-believe, per the Canadian Paediatric Society. Every child develops at their own pace; raise concerns, especially in more than one area, with your doctor.

Are the “terrible twos” normal?

Yes. The strong will, big feelings and defiance of age two are a normal, healthy part of developing a sense of self — the Canadian Paediatric Society lists showing increasing independence and defiant behaviour among the 24-month milestones. Simple choices, calm and consistent limits, naming feelings, and reconnecting after meltdowns all help. It’s demanding, but it passes.

How much should a 2 year old eat and drink?

Offer a variety of family foods at regular meals and snacks, with iron-rich foods still important (about 7 mg iron a day for 1–3 years), per the Canadian Paediatric Society. Keep milk to about 500 mL a day, in a cup, and offer water with meals. From age 2, many families move to lower-fat milk — ask your provider. Let your child decide how much to eat; appetites swing normally.

How much sleep does a 2 year old need?

A 2 year old usually sleeps around 11 to 14 hours over a 24-hour period, per the Canadian Paediatric Society, typically still with one afternoon nap. As children approach 3, total sleep eases toward 10 to 13 hours. A consistent bedtime routine, a calm wind-down, and avoiding late naps all help. A comfort item is often welcome.

What comes next after 2 years?

Over the next year, children build toward the Canadian Paediatric Society’s 3-year milestones: running easily, jumping in place, walking stairs with alternating feet, building taller block towers, speaking in short sentences, asking lots of questions, and beginning to take turns. Keep talking, reading, playing and offering safe independence to support the way ahead.
