And Cricket's back here for now. It went about as I expected:
Phase 1: Hyperdrive, hypersilly with the other kids, running around in circles, talking a mile a minute, volume level 11. Doesn't want me to touch her.
Phase 2: Shutdown. Lying down on the couch, talking about sleeping.
Phase 3: Clinginess and wanting to be treated like a baby, interspersed with some remaining spurts of energy. Talks about being sad, doesn't want to see the other kids, doesn't want me to leave her sight.
Phase 4: Screaming and crying.
Phase 4 is still going.
At the same time, as soon as she started saying all sorts of crazy stuff as she stepped in the door, and as soon as she said "Mommy will you pick me up" and I held her, it all washed over me like a wave. My deep love for this little girl who is hurting, who was hurting, who has been hurting.
