My first stared walking exactly on her first birthday. I mean, she would walk a couple of steps here and there before, but right on her birthday she walked like she never did anything else lol. They all start on their own time. Some with 10 months, some at 14.
my son is 10m and takes a few steps but would rather crawl. you can practice having her stand first or holding her hand while taking steps. but my doctor said the latest would be 18months in some cases.
