At what age do you get concerned that a child isn't definitively walking on their own?

I'd say anywhere from 16-24 months old. I didn't start walking until I was almost 24 months (2 yrs) old, while my twin brother was already walking for 6 months at that point. I turned out fine though.
Seeing a pediatrician would be a good idea for this kid, just to examine for any possible mental or physical handicaps that are delaying gross motor skill development. Most healthy kids hit the milestones around the same age - standing with assistance around a year old, and the first steps follow soon after.1
