When Do Babies Crawl? Plus, More Key Milestones for Baby's First Year

Learn when many babies reach key milestones in their development, including crawling, walking with support, and learning to say first words. 

During their first year of life, babies reach key milestones at an amazing rate. From cooing to crawling and more, these milestones offer clues to how your baby continues to learn and grow in this whirlwind first year.

Learn more from Scripps Pediatrician Dr. Olga Rose on key milestones during your baby’s first year: 

But when do babies start crawling?  And what other milestones should you expect your baby to reach at certain ages? Our parent’s guide will help you track key points in your baby’s physical, behavioral, motor (movement) and cognitive development. 

The points in this parent’s guide are listed based on the ages that most babies reach these milestones, as reported by the AAP, the CDC, and leading children’s hospitals. 

Every baby is different, so don’t worry if your baby doesn’t reach one of these milestones at the exact points we’ve listed. There’s actually a fairly wide window for babies to reach different milestones.

If your baby doesn’t reach a milestone at the point we’ve listed, they’ll likely reach this milestone within a few months. Some babies take longer than others to reach a milestone, and others even skip over milestones.

Your doctor will help you track your baby’s progress through key milestones, and let you know if your baby is experiencing any true developmental delays. If you have any concerns about your baby’s development, let your doctor know.
