Snarky Mom has a great post on The First Day. Really helpful recommendations for how to interact with the new child who has shown up on your doorstep. Welcome her in and let her go to the bathroom. Super important. She's probably nervous and you don't want her peeing on your floor.
She also has a post on questions to ask when you get The Call. I'd been meaning to start my own list, but she's done the work for me.
Also helpful--The Paperwork.
Joyful and Triumphant
