Anna has an old stethoscope that she plays with a lot. I think it helps her with nerves in the doctor's office knowing that she has a "toy" that the doctor also has. She likes to sling it around her neck then walk over to us, try to put the ear pieces in her ears and listen to "things". Sometimes those "things" she listens to turn out to be the couch or the pillows. But we end up helping her place the ear pieces in her ears and let her listen to both our hearts and hers. She thinks that's pretty great.
