I'm Amazed

So, we put Audrey in a second crib in Hannah's room in the past few days. We had put off doing this for the longest time, because I just couldn't handle the battle I was sure it would be. Just now, I laid both girls in their respective cribs for a nap. There was about 3 minutes of fussing, not even really crying, and then they were both out. They LOVE being in the same room. The first thing Hannah says when I get her out of her bed is, "Audrey?" Why did we keep Audrey in the pack and play in our room? Why didn't we do this months ago?
