Some schools require a physical be done within a certain time frame before the child starts. If your son's school hasn't given you a form to have your doctor sign off on, I wouldn't worry about it.

Our ped office has us go back for yearly well checks even though my son is up to date on vaccines also. They do give us paperwork for daycare to show that he is up to date

I know a certain ages that would want them to come in for checkups. Bryce does not do well at the Dr.'s . He really never gets sick. Thanking God! Just call an inquire if they need to see him for well visits. Does he have another doctor that see just for autism?
I have an appointment with one , that his doctor referred us to.

I work in the school health room. Every state is different on requirements. Some will allow you to waive getting the shots, some require a medical release form. http://www.nvic.org/Vaccine-Laws/state-vaccine-... If you do not want any more vaccines find out what is required per your state guidelines.

I meant to say, 'that his last visit was Jan 2013'.
