Babies typically start to crawl between 7 and 12 months of age, although some may begin as early as 5 or 6 months, and others may start a bit later—up to around 12 months. Crawling is a milestone that can happen in various styles, such as the classic hands-and-knees crawl, commando crawl (pulling themselves along on their tummy), bear crawl, crab crawl, or scooting while sitting. The process leading up to crawling usually begins with tummy time, muscle strengthening, rocking on hands and knees, and attempts to move forward or backward. Sitting up independently and developing arm and leg strength are also important precursors to crawling. Babies often show curiosity and motivation to move toward objects or parents, which encourages their crawling development. Some babies may skip crawling altogether and move directly to other forms of mobility like scooting or walking. It’s important for babies to have a safe and stimulating environment to practice these skills. If a baby is not showing signs of mobility by about 12 months, consulting a pediatrician is advisable. In summary:

• Typical crawling age: 7 to 12 months
• Earlier or later crawling is normal
• Various crawling styles exist
• Tummy time and muscle development precede crawling
• Motivation and safe environment help babies learn to crawl
