We've pretended to be grocery store clerks and postal carriers, bank tellers, day care providers, teachers and librarians, several times, but today we thought of a new pretend profession:
Pharmacists!
We emptied some of our cheap bubble containers and pill boxes, and gathered ointments, creams, lotions, dried beans (for pills) and all other pharmacy-related objects we could find to set up shop.
We also provided a preparation 'room' where they could mix their medicines for their customers (me).
Give them a table top and toy phone and let em go to work!
