Oh, I am a naive mother.
We spent a few days preparing, being all happy and breezy about how great it would be at the dentist's office. We went to the dentist's web site and looked at photos of the office and talked about everything that would happen there. She'd even been playing "dentist" with her dinosaurs. One dinosaur would be the patient, one would be the dentist, and one would be the hygienist. I figured that since she knew and could pronounce the word "hygienist" that we'd be OK.
WCK was perfectly fine ... until the hygienist suggested that she sit in the chair. What happened was so traumatic that I can't bear to recount it in words. Instead I will use photos.
