My wife is 32 weeks pregnant, how often should be seeing her OBGYN at this point? There seem to be no complications with her pregnancy.

If she is having a normal pregnancy, there is no need to see an Ob-Gyn at all. A midwife or practice nurse can provide all the care she needs at the moment. It depends on where you live, but at 32 weeks, one visit every two or three weeks is average.
