Nurse talking with parents of 6 mo infant about gross motor development. Which gross motor skills are expected in next 3 mo? (Select all that apply.)

The correct answer is A, B, and D. By 9 months, infants typically develop the ability to roll from back to front (choice A), bear weight on legs (choice B), and sit unsupported (choice D). Rolling from back to front demonstrates improved core strength and coordination. Bearing weight on legs indicates developing leg muscles and balance. Sitting unsupported signifies improved trunk control and balance. Choices C and E involve more advanced skills typically seen around 9-12 months. Choice C, walking holding onto furniture, is usually seen around 10-12 months, and choice E, sitting down from a standing position, typically emerges around 9-12 months.
