Alexa is the Doctor

Oliver threw up at a friend's house the other night, we think caused by something he ate.

Alexa: "Why did Oliver throw up?"
Us: "Something in his belly needed to come out."
Alexa: "Maybe it was the pizza crust."
Us: "Hmm, maybe [definitely was not]."
Alexa: "Oh yes, I think so. It was the crust."

Dr. Alexa then proceeded to pull out her friend's doctor bag and insist on "taking his temperature" and hearing his heartbeat.
