starting to crawl but lazy

So this is my son is he learning to crawl now which is so exciting and I encourage it and help him along as much as I can. My question is does anyone have a baby that's a lazy butt and just doesn't care to lift themselves up with their hands during tummy time? My son does the skydiving pose lol then the other pictures are of him trying to crawl and get his knees up. Is it normal for him to face the floor when learning to crawl?
