All over the place!

Ryan started crawling a couple of weeks ago and she is now all over the place. She doesn't do the army crawl....she does the full on crawl! She is so cute, but I'm quickly learning that I have to watch her extra carefully around everything, esp. since she started to pull herself up onto things. She now tries to pull herself up to get to the buttons on the TV, pulls herself up when she sees something on the couch, etc. She's only stood up a couple of times, it's usually a kneeling position, but either way, it makes me nervous that she's going to fall over. I don't know when most babies do these things, but she still seems kinda young (6 1/2 mo.) to me to be doing this. She doesn't have her balance down yet, which usually results in me catching her as she starts to fall over. I haven't let her crawl on the tile yet b/c she still will face plant or sit up and lose her balance and fall over and I don't want her hitting her head on the tile.
Although she's getting into everything, she's so much fun! She has a walker that she likes to walk around in usually resulting in her following me around while I'm cleaning, taking a shower, or even going to the bathroom. She wants to be wherever I am! Every stage has been so much fun and I look forward to continuing to watch her grow!
