Hypochondriac?

For Colter's birthday we got him a doctor's kit and boy does he love it! He now walks around telling me that he is "sick" and that I need to "take temp." Then after I take his temperature I have to give him "his medicine," check his heart and then tap his knees. When I tell him he is all better he says "NO MOMMA.....SICK!" Oh boy...what did we start?
