The finding that a 10-month-old infant sits with support by leaning on hands is an important indicator of developmental milestones. By 10 months, infants typically progress to sitting independently without support, which signifies a better core strength and balance development. While some infants may still rely on support in varying capacities, consistently needing to lean on hands for support could suggest delays in achieving this milestone.

The other options represent typical developmental skills observed in 10-month-olds. Pulling themselves to standing shows emerging lower body strength and coordination. Creeping on hands and knees is a common mode of locomotion that supports muscle development and coordination. Taking intentional steps while standing demonstrates significant progress in gross motor skills and balance. Thus, the finding about sitting with support may warrant further evaluation to ensure the infant is developing as expected.
