When do babies start crawling?

The AAP says babies usually master crawling between 7 and 10 months. A few never crawl at all, and get around in other ways.

How crawling develops

Before they crawl, babies may rock on their hands and knees or push themselves backward. The arm and back strength they build from about 5 months helps prepare them.

Babies who don’t crawl

Some children scoot on their bottoms or slither on their stomachs instead. The AAP says that’s no cause for concern, as long as your baby is coordinating each side of their body and using each arm and leg equally.

If you feel your child isn’t moving normally, talk with your pediatrician.

Keeping a crawling baby safe

  • Keep small objects out of reach.
  • Use sturdy gates at the top and bottom of stairs, and don’t let your baby use stairs alone.
  • Pillows and cushions can make a safe obstacle course, as long as you stay with your baby.
