Probably down to the individual hospital / caregivers I guess... I was 110 when I fell PG, I was weighed at my initial appt & again at my 41 week appt & not in between
My weight wasn't mentioned once & I had a successful VBAC.

ETA - actually, the Dr I saw at my 41 week appt was on the phone to someone asking a question, I can't remember about what now & he mentioned my BMI to them (it was over 40 I think). That was the only time I even had a hint that anyone thought it might be a problem.

ITA with the others, don't put up with any rude treatment. Myself, I would be happy to hear constructive advice or instructions, but no-one should make you feel crappy.
