At what age can a child start walking without support?

Appeared in: RUHS, Jaipur, PB B.Sc Nursing Entrance-2020

Explanation

The typical age for a child to start walking independently is between 12 and 15 months.
This milestone follows a predictable sequence of gaining strength and coordination, including sitting, pulling to stand, and cruising.
The 13-15 month range is the most accurate representation of when independent walking is established, as confirmed by pediatric development charts.

Why Other Options Were Wrong

Option B: At 6-8 months, an infant's primary gross motor achievement is sitting without support. They lack the leg strength and balance required for walking.
Option C: By 18-20 months, a child is typically well past the initial walking stage and is developing more advanced skills like running and climbing stairs.
Option D: At 8-10 months, an infant is learning to pull to a stand and 'cruise' (walking while holding onto furniture). They do not yet have the balance to walk without support.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Pediatric Gross Motor Development Milestones as background academic context rather than a clinical decision trigger.
Nurses use developmental milestone charts during well-child visits to assess a child's growth and identify potential developmental delays.
Providing anticipatory guidance to parents about what to expect next helps them create a safe environment (e.g., child-proofing the house before the child starts cruising and walking).
What if? If a child is not walking by 18 months, it is considered a developmental 'red flag'. The nurse should recommend a comprehensive developmental evaluation by a pediatrician to rule out underlying neurological or musculoskeletal issues.

How to Approach the Question

Identify the core question, which asks for the specific age range for a key developmental milestone: walking without support.
Recall the typical sequence of gross motor development in infants: sitting -> crawling -> pulling to stand -> cruising -> walking.
Evaluate each age range provided in the options against this developmental sequence.
The 6-8 and 8-10 month ranges are too early; these correspond to sitting and cruising.
The 18-20 month range is too late; this is when running begins.
Conclude that the 13-15 month range is the only option that aligns with the established norm for independent walking.
