Which finding suggests successful developmental progress for a 19-month-old?

Successful developmental progress for a 19-month-old can be indicated by the ability to pull up to stand. At this age, children are typically developing their gross motor skills and are expected to be able to pull themselves up to a standing position, which is a key milestone in the development of mobility and independence.

Pulling up to stand shows not only strength and balance but also the readiness to learn more complex skills such as walking. This ability reflects a healthy engagement with activities that promote both physical development and exploration of their environment. Mastery of this skill also sets the stage for further motor skills, such as cruising along furniture and eventually walking independently.

Drinking from a bottle, while a common behavior for toddlers, does not represent a significant milestone at this age, as many children are transitioning to cups. Not walking independently at 19 months is a sign that may require further evaluation, as many children are able to walk by 12-14 months. Watching excessive television does not correlate with developmental progress; rather, it may suggest a lack of engagement with physical activities or social interaction, which are crucial for a child's growth during this stage.
