3. Belly or Commando Crawl
Baby propels himself forward but keeps his belly on the ground. Enjoying the feeling of being grounded, your little one both wants to move around and be well rooted. He is still developing the core strength to lift his belly and may switch to a classic crawl after a while.

4. Bottom Scooter
Like your puppy when she has an itchy butt, your baby sits on her rear and uses her arms to propel herself forward. A personable infant, she doesn’t want to miss out on anything. This way, she can still be part of the conversation even while she moves around.
