Nervous for tomorrow

So tomorrow we have our little guy's 2 year check up. This is the appointment we will start his immunizations. I know he will be fine but I don't know anyone that likes to see someone having pain inflicted on a little one. I am also thinking about the last appointment we went to and he told the doctor no and said she was bad. I am not sure if there are enough treats in the world to keep him calm and happy. Caleb is taking tomorrow off to go with us to the doctor. We have a few errands that have to get done tomorrow after our little guys appointment. I hope he holds up ok. I am keeping my fingers crossed that all goes well tomorrow.
