How long is it appropriate for a 15-month-old baby to walk?

For a 15-month-old baby, walking for 30 minutes to 1 hour per day is appropriate. This duration meets the baby's physical development needs without placing excessive strain on their bones and muscles. Walking practice can be done indoors, but ensure the surrounding environment is safe, free of hazardous objects and obstacles, allowing the baby to move freely and try different walking styles and speeds. Outdoor walking practice is also beneficial; choose open, flat, obstacle-free areas such as parks or playgrounds.
