Blair's first night with memaw...

So my mother-in-law gave Brian and me a gift card to a nice restaurant for Christmas along with a promise to keep Blair when we decided to use it. Super nice gesture, right? Well we're going to use it tonight and I am so antsy and anxious I can hardly stand it. Blair hasn't stayed with anyone but us since she was born (aside from daycare, but that's different in that I've gotten use to it and it isn't necessarily a choice...just something we have to do). I know she'll be fine, but I am freaking out! Please tell me leaving her for a few hours here and there will get easier!?!
