Which gross motor milestone is expected for a 6-month-old infant in the next 3 months?

• A. Rolls from back to front
• B. Bears weight on legs
• C. Walks holding onto furniture
• D. Sits unsupported

Answer: (D)

Infants develop gross motor skills in a relatively predictable order: trunk control develops first, then sitting, then crawling, and finally standing or walking. At six months, a baby has gained enough trunk strength to sit with support, and many begin to sit briefly without support as they approach seven to nine months. Because the question asks what milestone is expected in the next few months, sitting unsupported is the natural progression from sitting with support and aligns with the typical window around 7–9 months. Rolling from back to front usually happens earlier, around four to six months, so it’s already established by six months for many infants. Walking while holding onto furniture is a later milestone, typically around nine to twelve months. Bearing weight on the legs can occur as infants start standing and bouncing with support, often earlier than sitting unsupported but not the new, next-step skill at this age.
