What mobility milestone is typically expected for a 1-year-old?

At the age of 1, children typically reach significant mobility milestones, and one of the key milestones is pulling up to a standing position and walking with assistance. This means they can use objects or a caregiver for support as they begin to explore an upright position.

During this stage of development, many infants will have mastered crawling and may be beginning to pull themselves up using furniture or other stable objects. While some children may start to take independent steps around their first birthday, it is more common for them to still rely on support. It is a time of exploration where they are gaining strength and coordination needed for walking independently, which typically occurs slightly later, often between 12 and 15 months.

The other options describe skills that are either not developmentally expected at this age or occur after this milestone. For example, running without assistance and walking independently might not be consistent for all children at this stage, while crawling alone would typically have been mastered earlier in their development. Therefore, the correct answer regarding the expected mobility milestone for a 1-year-old is pulling up to stand and walking with assistance.
