The ability of an infant to maintain an upright posture while seated in a stroller is contingent upon the development of sufficient muscular strength and postural control. Typically, this milestone is achieved gradually over several months, following the acquisition of head control and the ability to sit unsupported on the floor for brief periods.
Proper postural support is crucial for an infant’s musculoskeletal development and comfort while using a stroller. Premature or overly early use of an upright stroller position can potentially strain the infant’s developing spine and core muscles. Waiting until the infant exhibits consistent, independent sitting ability minimizes this risk.
