At what age do infants typically transition from a quadruped position to sitting?

The transition from a quadruped position to sitting typically occurs around 6 to 7 months of age in infants. At this stage, many babies develop the strength and coordination necessary to pull themselves into a sitting position from being on their hands and knees. This milestone is important as it demonstrates not just physical development, but also an increase in balance and core strength, which are foundational elements for further motor skills such as crawling and eventually walking.

Infants at this age have usually acquired sufficient muscle control to stay upright in a sitting position, allowing them to engage more with their environment. This sitting capability provides opportunities for exploration and interaction, crucial for cognitive and sensory development. Thus, 6 to 7 months marks a key development phase in an infant's ability to navigate their world.
