Seventeen months brings real speed. Your toddler is likely attempting to run — a stiff-legged, arms-forward dash that has more enthusiasm than control. They may also be climbing playground structures, walking up stairs with one hand held, and trying to climb out of their crib. Their body is stronger and more coordinated than even a month ago, and they need activities that match their intensity. Sitting still is not on the menu.
6 Gross Motor Activities for 17-Month-Olds
-
Living room relay. Place a toy at one end of the room and a basket at the other, then ask your toddler to carry the toy to the basket and come back for the next one — this run-walk relay builds endurance and purposeful fast movement.
-
Stair walking with help. Hold your toddler's hand and let them walk up and down stairs using alternating feet as much as they can — even if they revert to two-feet-per-step, the attempt builds leg strength and balance.
-
Jump attempt from a low step. Stand your toddler on a very low surface like a thick book or the bottom stair step and hold their hands while they try to jump off — most 17-month-olds will step rather than jump, but the intent teaches them to push off with both feet.
-
Toddler limbo. Hold a pool noodle at your toddler's chest height and gradually lower it so they have to bend more each time to walk underneath — this builds core flexibility and teaches body awareness in motion.
-
Pushing a heavy box. Fill a cardboard box with books and let your toddler push it across the floor — the heavy resistance strengthens their legs and core while teaching them to generate sustained force.
-
Walking on a balance beam. Lay a wide board flat on the ground or use a low balance beam, and hold your toddler's hand while they walk along it — this narrow path demands focused foot placement and single-track balance.
Safety Note
Running toddlers fall differently than walking toddlers — they go down harder and faster, often hitting their face or forehead. Keep play areas free of furniture with sharp edges, and make sure the running path has no slippery rugs or transitions between flooring types.
Best Surface for 17-Month-Old Motor Play
Running attempts and jump landings generate significantly more force than walking falls. A memory foam play mat absorbs that higher impact, protecting knees during tumbles and cushioning the inevitable face-first falls that come with learning to run. Shop Poco Koko play mats →
