DD2 = "booboo animal doctor"
DD4 = "sign twirler" (those folks who hold advertising signs on street corners)
DD6 = "veterinarian" (still about the booboo animals)
DD8 = "veterinarian who engineers animal prosthetics"
DD10 = "ethicist" (after confirming that this was a real job)
DD12 = "photographer or veterinarian"

She's always been surprisingly consistent. I have to admit from an adult perspective the ethics thing is the most interesting.
