Growing so fast

Its hitting me how fast Leiland is growing. His crawing is getting faster and farther by the day. He will actually crawl to me, instead of crying for me. We installed a baby gate last night at the top of the stairs which is crazy to me. We also moved his mattress down so he doesn't fall out. Now that he is crawling he goes to the couch or any other location just to stand up. THis however leads to numerous falls. He wants to walk, but he can't. Still no teeth, but I expect maybe in the next month we should have one. I also think he will be walking around 10 months, he is getting so good with his balance and coordination. He isn't talking a whole lot, I think he is more concerned with walking and crawling. He still babbles and squeals but not really trying any words at this point.
