Around 12 to 15 months, which motor ability is typically not yet developed?

Around 12 to 15 months, children are consolidating basic gross motor skills like standing, cruising, and taking independent steps. Jumping in place is more advanced and typically appears later, around 18 months to 2 years, because it requires enough leg strength, balance, and coordinated explosive power to lift both feet off the ground simultaneously. That’s why this ability is not yet developed for most children in this age range. Walking in a straight line is a refinement of gait that many toddlers begin to demonstrate as they gain balance and coordination during this period. Sitting without support is accomplished much earlier, usually by about 6 months, so it’s well established by this age. The option about speaking in two-word phrases is a language milestone, not a gross motor skill, and language typically progresses separately from motor milestones, advancing after the first year.
