Belly creepers usually begin crawling earlier than four-on-the-floor crawlers because they don't have to get up on their hands and knees, which requires greater strength and balance. The baby will use both legs depending on the direction in which he intends to go (forward or backward).

Once your baby is doing the classic hands and knees crawl, you can even help encourage them with crawling toys that they may want to reach.They choose to stay upright because it helps them move quickly and keeps their hands free to pick a toy up along the way. He places weight on one leg, while bending the opposite leg to propel himself forward, using the hands to maintain direction and control.

Asymmetrical crawling is categorized as when babies get around by primarily using one side of their bodies.

The only thing that parents can do is encourage tummy time to ensure that baby does some sort of crawling before he begins to walk. They'll alternate arms and legs, getting the arm on one side to hit the floor at the same time as the leg on the opposite side.

With the "classic crawl," the baby is on all fours (hands and knees) with their tummy off the floor.You can also use different crawling toys to show your baby how to crawl or encourage them to chase after. Your little one doesn’t need to hit traditional crawling milestones to gain independence and develop walking skills. The bear crawl is similar to the classic crawl, but instead of being down on their knees, the babies keep their legs straight.
