Preparing for sleepaway camp

That's what we are calling A's time to stay with Nana while Dh and I head to Alaska next week. A has never spent a day away from me, nor a night. And we will be gone for 6 nights! So tonight, for the first time ever, someone other then Dh or I put her to sleep. Nana read her her story and put her down....and she went right to sleep. If she wakes up tonight and calls out, Nana is going to take care of her. A knows we are practicing and right now seems pretty excited about sleep away camp. I am excited about our trip, but very nervous about leaving her for the first time for so long. I know she will be happy with my mom, but wow, it will be hard for me.
