Gross Motor Milestones: From Newborn to 2 Years

What Are Gross Motor Skills?

Gross motor skills involve the large muscle groups used for whole-body movements: rolling, sitting, crawling, pulling to stand, and walking. These skills develop in a predictable sequence, though the exact timing varies considerably between children.

Milestone Timeline

0–3 Months

• Lifts head briefly during tummy time
• Holds head up at 45° during tummy time by 2 months
• Kicks legs and moves arms

4–6 Months

• Rolls from tummy to back (usually first), then back to tummy
• Holds head steady when upright
• Bears weight on legs when held standing
• Sits with support

7–9 Months

• Sits independently
• Gets into crawling position and begins crawling (some babies skip this)
• Pulls to stand while holding furniture

10–12 Months

• Cruises along furniture
• Stands briefly without support
• May take first steps — most babies walk between 9 and 12 months, but up to 15 months is normal

12–24 Months

• Walks independently and steadily
• Climbs onto furniture
• Runs (though falls frequently)
• Kicks a ball
• Walks up stairs with support by 18–24 months

Red Flags to Discuss with Your Doctor

• Not rolling by 6 months
• Not sitting independently by 9 months
• Not standing with support by 12 months
• Not walking by 18 months
• Loss of previously acquired motor skills at any age

The Role of Tummy Time

Supervised tummy time from birth is essential — it builds the neck, shoulder, and core strength that underpins all gross motor development. Start with a few minutes several times a day and gradually increase.
