5 year check up

Chance sitting on the table waiting for the Doctor.
At Chance's 5 year check up in February he was such a great little boy. He did everything the nurses and Doctor asked him to including going into another room by himself to do his sight and hearing tests while I filled out paperwork. Both of which he passed with flying colors. He really liked the hearing test because he got to wear a big headset and tell them which side the sound was coming from.
He is in the 97th percentile for height (47 inches tall) and weight (50.5 pounds) which means he is large on average but perfectly proportioned. His BMI is right in the middle of the scale which basically means he not underweight or overweight. In short he is just perfect.
He received a couple shots, flu and Hep A and they took his blood to check his cholesterol even though I don't think they needed to but it's ok because now we know for sure he does not have any cholesterol problems.
The Doctor did notice a heart murmur when he was listening to Chance's chest. A murmur is simply a small irregularity in his heartbeat. Now here is the thing, after doing some research I found out that it is very possible to have a heart murmur due to stress or exercise as well as actual heart conditions. Upon finding this they wheeled in a small EKG machine and hooked up little wires to sticky things all over Chance's chest and belly. He thought it was fun because he looked like a robot (and wants to be a robot for this Halloween), that EKG did not find any irregularity. Since no other Doctor has mentioned a heart murmur to us at all in the past and the small EKG returned nothing irregular and since Chance shows no other symptoms of heart problems (easily tired, does not like physical activity, chest pain...) we have decided not to do any more testing right now. We could do further EKGs and MIRs and different things but why put us all through that for what is likely nothing.
I promised him a chocolate milkshake if he was good and as we were leaving the office he said "Do I get a milkshake? I only cried a little when they shot me". Of course we stopped for shakes, I mean he was shot for goodness sake and he only cried a very little.
