My daughters second graade teacher hated everything we brought in.....turtles, frogs, bug, ultrasound pictures( of her kidneys), ekg strips, and photos from an upper GI, all the wrist bands from my daughters hospital visit, the girl spent 5 months sick... the only place we went was to the doctors office and hospital. SHe thought i was very strange, although all the kids thought it was cool to see the inside of her stomach. Hopefully this years teacher is a little more open to out of the box thinking.
