At what age should a child be able to walk independently without support?

GROSS MOTOR MILESTONE — independent walking: Most children walk independently by 12 MONTHS (9-15 months is the normal range). RELATED MILESTONES: 6 months: sits with support; 9 months: pulls to stand, cruises (walks holding furniture); 12 months: stands alone briefly, takes first independent steps; 15 months: walks well independently; 18 months: runs (though falls frequently). RED FLAGS requiring developmental evaluation: not walking by 18 months; walking on tiptoe persistently; significant asymmetry in movement. NCLEX NURSING ROLE: Assess developmental milestones at each well-child visit; use standardised screening tools (Denver Developmental Screening Test); educate parents that range variation is normal but significant delays need evaluation; refer for early intervention services if delays are identified.
