Taking interest to be amongst playmates by going out of parents company is…

Concept

Developmental psychology tracks a well-known transition within childhood — roughly ages 6-12, sometimes called the "gang age" — where a child's dominant social orientation shifts away from the family and toward same-age peer groups. This later phase of childhood is marked by children actively seeking independence from parental supervision, spending increasing time with playmates, and forming collective peer-group ties that begin to outweigh the pull of parental company.

Application

The stem describes precisely this shift — a child stepping out of the parents' immediate company specifically to seek and prefer the companionship of same-age playmates. That deliberate preference for peer company over parental closeness is the hallmark behaviour of this later-childhood "gang age" transition.

Cross-check / Contrast

• Adolescence: by this stage, peer-centred social life is already the long-established norm, layered with additional concerns like personal identity and independence from society at large — a later, already-settled pattern, not the newly emerging shift described.

• Pre-childhood (early childhood): social life at this stage still centres on the parents and caregivers; children remain largely dependent and home- or supervised-play oriented, not yet actively choosing peers over parents.

• Infancy: no independent peer orientation exists at all at this stage; an infant's entire social world is the caregiver.

Result: the behaviour described is associated with later childhood.
