even during times when DD has been sick enough to be seeing doctors left and right, I'd still take her to her well child appt. Why? because not only did/does it show that my DD *can* be healthy

but it also helped DD not automatically associate doctors with pain. She LOVES her wellchild appointments. She gets to talk to (and hug.) a doctor, not get a shot, and 'earn' a ton of stickers for it. As far as she is concerned, well child appointments ROCK. It also can help keep track of things like her development that you do not discuss during a normal 'she is sick lets fix this' appointments.
I personally loathe doctors, I much rather wallow in pain for three weeks than see one. Yet I never completely miss my once a year 'well adult' visit. I may post pone it a month or two, but miss altogether? nope.
Also, even if 'kids sometimes develop tics' I would have been down right mad to have it dismissed that easy. a tic can be an early sign of something much worse, and why take that chance?! Personally, I would be finding a new ped, he seems to be too dismissive for my tastes. but, your you and it can be different.
one last thing... even if it is a life or death, never will change thing like an epi-pen. if you have not seen the doctor for a regular visit, they are well within their right to not prescribe it. as far as they are concerned you moved on to another ped and may already have a script, or your kid could have moved out of state (as in a divorce). doesn't matter what the medication is, the point is that it IS a prescription required medication, and they doctor needs to know the patient.

silly I know, but still true.
