Physiological: In general, babies are able to walk with the help of chairs and strollers at the age of 10 months, and most of them can walk independently at the age of 12-14 months.

Parents need to pay attention to the fact that their one-year-old four-month-old baby can’t walk, and if necessary, take the baby to the hospital for evaluation by a professional doctor.
