Which motor milestone appears first in infancy: rolling from tummy to back or rolling from back to tummy?

• A. Rolling from tummy to back
• B. Rolling from back to tummy
• C. Sits without support
• D. Crawling

Answer: (A)

Infants typically roll from tummy to back before rolling from back to tummy because early movement around the trunk and shoulder region is easier when placed on the stomach. When prone, a baby can use a quick twist of the hips and push with the arms to rotate onto the side and then onto the back with momentum. This first rolling motion demonstrates developing neck, shoulder, and trunk control in a more accessible position.

Rolling from back to tummy requires more strength and coordination, as the infant must lift and rotate the upper body from a more extended starting position and often fight against gravity to complete the roll. This milestone thus tends to appear a bit later than tummy-to-back rolling.

As for the other options, sitting without support and crawling occur after these rolling milestones, reflecting further development of balance, core strength, and coordinated limb movement.
