Awww poor little Cheri! I KNOW she'll be perfectly fine. They're probably kissing and hugging her right now. I bet they're even tickeling her little feet.
I would bring a blanket to hold her in and her favorite toy, although she'll probably be too tired to play with it. Just make sure you give her LOTS and LOTS of kisses from me, Codie and Katie! We'll all praying for Cheri!
