At what age can an infant first roll from the back to the side?

Rolling over from back to side reflects growing trunk control and coordinated use of the arms and torso. This early rolling movement typically appears as infants develop enough neck and core strength to rotate their upper body and shift their weight to the side. By about 2 to 4 months, many babies begin to roll from back to the side as they experiment with their new mobility and gain confidence in moving against gravity. 0 to 1 month is too early—the baby is mostly limited to reflexive movements and basic head control. 5 to 6 months starts to show more advanced rolling patterns, often from back to front, as part of ongoing motor development, but the initial back-to-side roll commonly appears earlier. 9 to 12 months is well beyond the typical window for first rolling movements, as babies at this age are usually crawling, cruising, or walking.
