8-months old and on the go!!!

So yesterday I was hanging out with Gavin in his room, change of scenery, and I could have sworn that he crawled. Now he has been doing the taking steps with his arms thing but then just flings his legs forward therefore falling on his belly, kind of making him look like a rocking horse. He actually did it so hard Friday at my mom's that his legs about went over his head, it was actually quite humorous. He had his slick footed jammies on last night that when he went to move his legs his just slid, this is why I say "I think he crawled". I don't know if it was a full-fledged crawl because he was sliding. I try to keep him in only a diaper so he can practice but when it's close to bedtime the jammies go on. It is going to be so much fun to watch him crawl around but oh gosh, are we ready for this?!
