In the traditional crawl, she'll first learn to balance on her hands and knees. Then she'll figure out how to move forward and backward from this posture by pushing off with her knees. But because crawling not a required building block for future motor skills, crawling is not technically a developmental milestone. In fact, many babies never crawl at all, and that does not indicate that something is wrong with them. By 6 months of age, infants have developed simple but consistent action schemes through trial and error and much practice.
Infants use action schemes, such as pushing and grasping, to make interesting things happen.
Here are some initial signs of the crawl development. Copyright 2000 KinderStart. Inc. All rights reserved.
