How cute is he?! Erwin the Little Patient, sold by the company Wild & Wooly is an interesting teaching toy, fun for all ages. He comes dressed as a patient in a dressing gown, but can be opened up for some internal organ education. From my guess, it looks like he has a heart, lungs, liver, stomach, kidney, bladder and intestines. For the future doctor it could be a wonderful tool for teaching children about health.
The only downside is that he’s currently out of stock (more to come though).
