At what age do infants typically begin to creep (reciprocal on all fours)?

Infants typically begin to creep on all fours around 8 to 9 months of age. This developmental milestone is significant as it marks a transition in gross motor skills, where infants coordinate their arms and legs to move in a reciprocal pattern. This crawling technique not only enhances their mobility but also aids in the development of strength, coordination, and spatial awareness. Creep crawling is also an important precursor to later skills such as walking. Most infants will start exploring their environment more actively at this stage, which contributes to cognitive and sensory development as they encounter new objects and surfaces. Understanding this timeline helps caregivers and educators support infants in reaching their developmental milestones effectively.
