Not sure about Little Einsteins, but Doc meets in front of the Disney Jr show pretty much all day at HS. DD adores Doc, and was thrilled to meet her when we were there last week. Also, if you are there in the evening, Doc is not there but her "clinic" where she meets is open and lit, and kids can play there and take pictures. DD spent at least a half hour there pretending to be Doc, and she had it all to herself!
