We were going to 2 clinics at the same time for just a little over a year, until we decided if we were going to switch or stay at our current clinic. It's funny, they are only an hour away from each other and one wanted him to come every 3 months and the other saw their patients every 2 months. I've often wondered about the "real" reasons for this. I want to believe the intention of every 2 months is truly for the best interest of the child, but I have to admit I've pondered wheter or not it was for revenue. I may be totally wrong, but it just seems the larger clinic which I feel is still agressive is every 3 mos and the smaller one, is every 2 mos.
I don't know which is the best. Quess every 2 mos if there are alot of health issues, but every 3 mos work for us since he is so healthy. I've beeen know on a few occasions to strectch it a few weeks past the 3 mos, but never more than 4 mos.
