Trying so hard

I was doing the laundry while Jax was having tummy time.  I walked into the living room and Jax has his knees under him working so hard to get somewhere. He worked and worked and worked at crawling.  He can push himself, but his face is face planted into the carpet.  He doesn't realize that he has to use his as to keep his face off the floor, yet.  He has also held his head up and then tried crawling/pushing himself. But much movement or actions follow through there.  He is still learning and soon will get the hang of it.
