LB's first accident :(

My son ALMOST has this whole crawling thing down! At the moment he is really good at rolling all over the floor, and he is practically army crawling. I don't know how he does it, but before you even realize, he'll get his legs stuck underneath of the couch, or he will be halfway across the room and you have to go pick him up and move him back to the middle of the living room (which is tiny, and so I have to move him often.) Today he was playing near our dining table (which is in our living room because it's an all in one kind of room-we literally do all of our living in our living room!) and my husband's coat was hanging on the back of the chair. He went to grab the coat and pulled the chair down on top of him!!! I was so scared and as I was pulling the chair back up, I kept repeating "Oh my God!!!!"
My son has had a few bumps on his head from falling over in the past, but never had an accident like this before. It scared me half to death! I held him for like a half hour and just cuddled with him....my adrenaline was pumping for a good 20minutes! This was Bryan's first real accident and he came out without a single scratch or bump! Thank God! I definitely DO NOT want him to get any older, because I know, with more mobility means more accidents. I do not do well with accidents and with babies getting hurt! :( SO please God, keep looking out for my soon to be crawling baby boy!!!
