Most babies take their first steps sometime between 9 and 12 months and are walking well by the time they’re 14 or 15 months old. Don’t worry if your child takes a little longer, though. Some perfectly normal children don’t walk until they’re 16 or 17 months old. During their first year, your baby is busy eveloping coordination and muscle strength in every part of their body. They’ll learn to sit, roll over and crawl before moving on to pulling up and standing at about 9 months.
