She rolled over!

Madolin rolled over for the first time today about 5 minutes ago. I had layed her down on the couch (I know, not good lol) and was on the computer and she started fussing, so I went over to see what the problem was and she was on her stomach! Her first real physical milestone! I was so excited! But doesn't this mean that she is getting bigger? It's all happening so fast! Time just flies.
