“When do babies start crawling? My child is 6 months old but not crawling yet, and I am starting to become worried by this as all my other kids were early movers.”

Most babies start crawling from seven to ten months. However, it is very important to note that some babies start crawling earlier and others never crawl. This is why crawling is no longer considered a developmental milestone. Look for other signs of physical development, like sitting up, rocking, shuffling, pulling himself up on the side of the cot. If you don’t see progress in his physical development, take him to see the doctor.
