Chances are, the night will be much more difficult for you than her. Tell her that you and daddy are going out for the night and she's staying with her aunt and her cousins. I bet she'll have so much fun that she won't even notice you're gone. *sorry* Also, don't let her know how nervous you are. If she picks up on it, she will be frightened. Make sure your sister knows exactly what the bedtime routine is, so she can follow it. I have no doubt that you'll be worried and missing her, but try to enjoy yourself. I don't know how old Rose is, but I'm guessing she's the same age as my dd. I know whenever my little one stays somewhere else, she tends to sleep better than when she's at home. Not sure why that is. Enjoy your kid free night! I bet when this one's over, you'll already be planning the next one!
