Key Takeaways
At 15 months, most toddlers have the 12-to-14-month skills the Canadian Paediatric Society describes and are building toward the next set at 18 months.
Gross Motor
A 15 month old often walks without help and may climb stairs with help or climb into chairs, building toward the skills the Canadian Paediatric Society lists at 18 months (walking well, climbing into chairs, climbing stairs one at a time with help). Give safe space to move and supervised places to climb.
Climbing changes what counts as out of reach. A toddler who can push a chair across the room can get to anything in it — blind and curtain cords especially. Tie cords up high or fit cord cleats, and check every room rather than just the ones your toddler usually plays in.
Fine Motor
A 15 month old uses a spoon (awkwardly), drinks from a cup, scribbles, and can put objects into containers and take them out, building toward the 18-month skills the Canadian Paediatric Society describes, like building a small block tower and turning board-book pages. Offer crayons, blocks and self-feeding practice.
Social & Language
A 15 month old uses several words, points to things they want, copies others, and may follow a simple instruction, building toward saying 20 or more words and pointing to named body parts by 18 months, per the Canadian Paediatric Society. Name things, read daily, and respond to their attempts to communicate.
DEVELOPMENT & PLAY
- Offer safe chances to practise independence — self-feeding, simple dressing, small choices.
- Provide crayons, blocks, stacking and posting toys, and books to read together daily.
- Name feelings and narrate your day to grow words and emotional understanding. Nothing on a screen does this better than you do — the CPS advises no screen time before age 2, and back-and-forth talk is what actually builds language.
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 — the bottle should be gone by around now.
- Offer water with meals and snacks; continue vitamin D for breastfed and partly breastfed toddlers.
HEALTH
- Check whether your province or territory schedules a 15-month checkup or vaccines — timing varies by where you live.
- Keep brushing teeth twice a day with a rice-grain smear of fluoride toothpaste — that amount is safe to swallow — and keep up regular dental visits.
أسئلة مكررة
What should a 15 month old be doing?
A 15 month old often walks without help, says several words, points, copies others, and may follow a simple instruction, building toward the Canadian Paediatric Society’s 18-month milestones (20 or more words, walking well, climbing into chairs). Every child develops at their own pace; raise concerns, especially in more than one area, with your doctor.
How many words should a 15 month old say?
There’s a wide normal range. The Canadian Paediatric Society lists saying 20 or more words among the skills most children reach by 18 months, so at 15 months many toddlers have a handful of words and are adding more. Pointing, gestures and understanding often run ahead of spoken words. If your toddler isn’t using any words or gestures by around 18 months, raise it with your doctor.
Does my 15 month old need vaccines?
It depends on your province or territory. Some schedule a checkup or vaccine doses around 15 months, while others give the relevant doses (like the second MMR or varicella) at 18 months or later, per the Canadian Paediatric Society, which notes timing varies by where you live. Check your local schedule or ask your doctor or public health nurse.
How much should a 15 month 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. Let your toddler decide how much to eat — appetites swing normally at this age. Avoid choking-risk foods and added salt and sugar.
How much sleep does a 15 month old need?
A 15 month old usually sleeps around 11 to 14 hours over a 24-hour period, per the Canadian Paediatric Society, on one or two naps. A consistent bedtime routine, a calm wind-down, and avoiding late naps all help. A comfort item like a blanket or stuffed animal is often welcome.
