I feel like maybe this little one should be a pediatrician...
We have a really cool place here locally called Kidscape. They have a mini kid-sized town for the kids to explore.
One of the storefronts in the town is a little hospital. It's just a tiny little room with a skeleton with magnetic bones, a little operating table, kid-sized doctors coats, random doctor tools, a baby scale and a little basket of babies.
This little cutie pie collected all of the babies and gave them all a check-up. She was here most of the time.
I absolutely love this place and the level of imaginary play they have when playing here. I would love to build a whole preschool around this idea of experiences while playing.
