Are pregnant women over 35 always treated as high risk or can they see a regular nurse-midwife or ob if in good health and no abnormalities w/baby?

Depends: On the OBGYN. But usually you will not be considered high risk for pregnancy without other medical problems. However, you are at higher risk to have a baby with a genetic defect such as Down's Syndrome. Talk to your OB about doing a triple screen and poss early fetal ultrasound during your pregnancy and weigh the pro's and con's. However, It's your choice if you want genetic screening.

Both: Yes there is some increase in risk after age 35 regarding genetic problems, developmental problems and complications of delivery. This does not mean that you can not delivery with a midwife especially if you have had normal deliveries in the past. Midwives often work in hospitals where MDs are available in case of unanticipated complications for you or your baby. Good prenantal care is best.
