Cultural practices that may delay the onset of gross motor milestones can include which of the following?

• A. Positioning, clothing, and toileting practices
• B. Dietary restrictions only
• C. Language development
• D. Genetic factors only

Answer: (A)

The key idea here is that how a baby is positioned and how much freedom of movement they have can directly influence when they reach gross motor milestones, like rolling over, sitting, crawling, and walking. Cultural practices that limit movement—such as tight swaddling, restricting active play, or clothing and routines that keep a child in passive positions—reduce opportunities to practice these skills. When a child isn’t encouraged to move and explore, their motor system may develop a bit more slowly, simply because they have fewer chances to practice the actions that build strength and coordination.

Dietary restrictions, language development, or genetic factors aren’t about how the child is allowed to move in daily routines, so they don’t explain delays in gross motor onset as a result of cultural practice.
