Key Takeaways
At 17 months, most toddlers are close to the milestones the Canadian Paediatric Society lists at 18 months.
Gross Motor
A 17 month old walks well, may climb into chairs and up stairs with help, and is steady enough to carry a toy while walking, building toward the 18-month skills the Canadian Paediatric Society describes. Give safe places to climb and space to move, and supervise closely.
All that climbing raises the question of when to move to a toddler bed. The usual answer is not yet — a crib is safer while it still holds, and most toddlers aren’t ready to stay in an open bed until closer to 2. The signal to switch is your toddler actually climbing out, not their age. Until then, mattress on its lowest setting and nothing in the crib to stand on.
Fine Motor
A 17 month old scribbles, stacks blocks, uses a spoon more neatly, and turns board-book pages, building toward the 18-month fine-motor skills the Canadian Paediatric Society lists. Offer blocks, crayons, simple puzzles and self-feeding practice.
Social & Language
A 17 month old copies the behaviour of adults and other children, uses a growing set of words, points, and may follow a simple instruction, building toward saying 20 or more words by 18 months, per the Canadian Paediatric Society. Early pretend play — feeding a doll, “talking” on a toy phone — often appears now. Narrate, name and read together, and put your own phone somewhere else while you do. Toddlers copy what they see, and words come from the back-and-forth.
DEVELOPMENT & PLAY
- Offer safe places to climb and space to walk and carry things.
- Provide props for early pretend play — a doll, toy phone, pots and spoons — and join in.
- Read daily, name objects and feelings, and model words and kind actions.
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.
- Offer water with meals and snacks; continue vitamin D for breastfed and partly breastfed toddlers.
SAFETY
- Anchor tip-prone furniture, add window guards, and gate stairs for a determined climber.
- Keep hazards out of reach, and supervise eating and climbing. Molars still aren’t fully in, so a 17 month old can’t grind food properly yet: quarter grapes and cherry tomatoes lengthwise, slice hot dogs lengthwise too, spread nut butter thinly rather than in blobs, and skip popcorn, whole nuts, hard raw vegetables and hard candy.
أسئلة مكررة
What should a 17 month old be doing?
A 17 month old usually walks well, climbs, scribbles, uses a growing set of words, points, copies others, and may start simple pretend play, 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.
Is pretend play normal at 17 months?
Yes — early pretend play, like feeding a doll or “talking” on a toy phone, often appears around now and is a healthy sign of developing imagination and language. It builds toward the more elaborate make-believe the Canadian Paediatric Society describes closer to 2 years. Join in and follow your toddler’s lead with simple props.
How much should a 17 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. Around 16 to 18 months the first molars and canines come through, and these bigger teeth can knock appetite back for a few days along with extra drool and fussiness. It passes, and it isn’t the start of picky eating. Keep added salt and sugar low.
My 17 month old only says a few words — should I worry?
Often not. There’s a wide normal range, and the Canadian Paediatric Society lists saying 20 or more words among the skills most children reach by 18 months. Understanding and gestures usually run ahead of speech. Keep talking, reading and naming. If your toddler isn’t using any words or gestures by around 18 months, or you have other concerns, raise it with your doctor.
How much sleep does a 17 month old need?
A 17 month old usually sleeps around 11 to 14 hours over a 24-hour period, per the Canadian Paediatric Society, often on one afternoon nap. 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.
