Gross Motor Milestones Baby Tracker by Age

Gross motor skills involve large muscle movements — rolling, sitting, crawling, standing, walking, running, and jumping. They develop from head to toe (cephalocaudal) and from the center outward (proximodistal). They are the foundation for all physical activity.

Head control → rolling → sitting → crawling/scooting → pulling to stand → cruising → standing → walking → running. Some babies skip or modify steps (like bypassing crawling) which is usually normal.

Not necessarily. Some babies go straight from sitting to pulling to stand and walking without conventional crawling. Scooting on the bottom is also a normal variant. Talk to your pediatrician if your baby isn't mobile in any way by 10–11 months.

Possible causes include low muscle tone (hypotonia), premature birth, limited floor time, underlying neurological conditions, or developmental delays. Many children catch up with early physical therapy. Most mild delays resolve on their own.

Yes — significantly. Daily tummy time builds the neck, shoulder, back, and core strength needed for all upcoming milestones. AAP recommends starting tummy time from day one for supervised, shorter sessions that gradually increase.

Not walking by 18 months is the main red flag. However, if your baby also isn't cruising or pulling to stand by 12–13 months, or if they were walking and stopped, discuss it with your pediatrician sooner.

Supervised tummy time, floor play, rolling a ball back and forth, push toys, obstacle courses with pillows, climbing on playground equipment, swimming, and active outdoor play. Minimize time in swings, bouncers, and walkers that restrict free movement.
