Which gross motor milestone is appropriate for a 5-month-old infant?

• A. Roll from abdomen to back.
• B. Roll from back to abdomen.
• C. Sit erect without support.
• D. Move from prone to sitting position.

Answer: (A)

At five months, infants typically begin to roll from the stomach to the back as trunk control and coordinated movement develop. This milestone demonstrates emerging gross motor strength that lets the baby change from a prone position to a supine one. Rolling from back to abdomen usually appears a bit later as the child gains more shoulder and trunk stability, not at five months. Sitting erect without support generally occurs closer to six to eight months, and moving from prone to sitting is a later milestone as well. So, the action most appropriate for a five-month-old is rolling from abdomen to back.
