The recommendation to delay the introduction of activity standers until around six months of age for infants stems from several developmental considerations. These devices support a child in an upright, standing position, allowing for increased mobility and exploration. However, prematurely introducing this type of support can potentially interfere with natural developmental milestones.
Waiting until approximately six months of age allows infants to develop sufficient head and neck control, trunk stability, and weight-bearing capacity in their legs. Premature use of activity standers, before these core muscles are adequately developed, may lead to compensatory movement patterns that could hinder the development of proper posture and gait later on. Historically, early introduction was sometimes seen as beneficial, but evolving understanding of infant biomechanics and motor development has shifted best practice towards a more cautious approach.
