One of the suggested play centers from The Itty-Bitty Bookworm lessons, Miss Polly Has a Dolly is for the children to have Dr. toys to pretend they are making their baby or dolly feel better. So I bought one at Toys r us. Caden was semi-interested in all the Dr. tools. I will be leaving that out for him to get familiar with. We talked about being sick and how the Dr. makes you feel all better.
