We had taken Brett and Casey to the doctor for their check-ups and child vaccinations. Both Brett and Casey were a little scared as another child had apparently gotten a shot and burst out crying. Casey went first and she came back into the waiting room and was crying. I took Brett in and he was distracted by the doctor and the shot did not really hurt him–he sort of laughed and said it was not too bad. We walked out into the waiting room and Brett started telling Casey that he did not cry and that she was a baby for doing so. Casey then proceeded to pinch Brett right on the arm where the shot was given and then he began to cry.
