I think that's pretty normal.

The first neuro I had saw me every 6-8 weeks. After he was no help at all to me, I fired him.

My second neuro saw me every 4 weeks until I started to get better. (I was in VERY bad shape when I first met her.) Since then, she saw me every 2-3 months and gradually she increased the time between my appointments to every 4-6 months.

I saw her last about 5-6 months ago and I'll see her again in a few weeks.
