Question: 1 / 400

What age is represented by an infant who can push up from their stomach onto their knees and rocks back and forth?

4 weeks

3 months

6 months

An infant who can push up from their stomach onto their knees and rocks back and forth is typically around 6 months old. At this age, infants are developing key motor skills, including the ability to assume a crawling position, which involves pushing up on their hands and knees. This milestone indicates that the child is gaining strength in their upper body and core muscles, as well as developing coordination.

Around 4 weeks and 3 months, infants are still primarily focused on basic reflexive movements and significant head control. By 8 months, many infants are not only crawling but may also be starting to pull themselves up to stand or even take steps while holding onto furniture. Thus, the characteristic movements of pushing up and rocking on knees specifically align with developmental milestones seen around 6 months of age.
