My crazy, tool man turned 4 right before Christmas. We took him to his well-child doctor visit/check up. As he is now a "big boy", he will only get annual check ups - it's kind of weird not going to the doctor's office every few months, now that all the kids are getting bigger. I told him straight-up that I was not sure if he would get shots or not, but that I needed him to be a big helper and listen to his doctor. He was an A+ patient. Listening, responding (most of the time), and having a positive attitude throughout the visit.
It came to shot time, get 4 now and no more until you turn 12 or half now (2) and the other half next year. As we did with Krista, we opted for all of them now - much better for next year's kindergarten check-up. He made a pouty lip at the news, but promised to be strong. I could not have been more proud. He laid still, did not cry when they poked him - even as he tensed up for each shot. He got to pick out a prize for his effort and was told he was the bravest 4-year old they had ever seen. I think that made him proud of himself because he kept saying that he was "a brave boy" for the rest of the day.
