Which of these actions is not a milestone for 4-12 months developmental stage?

1. Turning head from side to side while on stomach

2. Sleeping more than 8 hours at a stretch

3. Rolling over from stomach to back

4. Walking independently

The correct answer is: Walking independently

During the developmental stage of 4-12 months, significant milestones are focused primarily on physical mobility and sensory engagement. While infants typically start to roll over and may engage in turning their heads side to side, walking independently is a milestone generally observed later, around 12 months and beyond. By this stage, most children are gaining strength and coordination, which allows them to achieve skills like rolling over and sleeping for longer hours due to better-established sleep patterns and routines. However, walking independently represents a more advanced developmental goal that usually occurs after the first year rather than within the 4-12 month range. Understanding the timeline of developmental milestones is crucial for recognizing typical progress in infants, assisting caregivers and professionals in identifying any potential developmental delays.
