A nurse is teaching a group of parents about expected development of gross motor skills during infancy. The nurse should teach that the following developmental tasks are expected to occur in what order? (Move the Steps into the box on the right. placing them in the order of performance. use all the steps.)

A. Rolls from back to side typically occurs around 4 months of age, as the infant gains initial control of trunk and limbs. This is one of the earliest gross motor milestones. B. Sits steadily unsupported generally develops by about 8 months, showing further improvement in core strength and postural control. C. Rolls from back to abdomen follows around 5–6 months, demonstrating increased muscle coordination and control over the trunk and neck. D. Changes from prone to sitting usually occurs between 9 to 10 months and indicates advanced coordination, enabling independent movement and transition between positions.
