I'm glad you stuck to your guns - it's hard to do that sometimes! I'm overweight, and bigger than when I had DS. My Ob has never weighed me, never asked me my weight, never commented on size (most of my fat is on my hips and thighs, but I was close to 90kg when I got pg), never said anything about birthing choices (even though DS was an emergency c/s) and never suggested extra scans. He only ever occasionally uses the doppler (usually just listens with a stethoscope), and can easily feel fundal height. As someone else suggested - it's about doctor/midwife skills rather than anything else if you ask me! Also, do they see birth as something to be "managed" or a natural process that they're assisting with? Thankfully my Ob is the latter.
