Detailed explanation-1: -crawl. Moving by pulling with the arms, but not lifting the abdomen from the floor.

Detailed explanation-2: -The two main categories of crawling are belly crawling and criss-cross crawling, which is when the hands and knees of opposite limbs work together to move forward. Scientists have found that this type of crawling is beneficial for brain development and may even help the two brain hemispheres communicate.

Detailed explanation-3: -What is the difference between ‘crawling’ and ‘creeping’? Your babies are ‘crawling’ when they move around using the commando style tummy crawl. ‘Creeping’ begins when they lift their tummies off the floor and move around on their hands and knees.

Detailed explanation-4: -What is scooting? Scooting is one (adorable) way some babies get around when they first start moving independently. It’s a prelude to traditional crawling for some babies, but others prefer scooting to get around and may stick with it until they’re ready to start pulling up and try walking.
