I had a sweep done with #1 - that was in St. Louis, MO. It did absolutely nothing for me.
I'm sure my doc would have done one now, but she couldn't get much past my "outer cervix" (apparently, for second+ babies, your cervix dilates more in a cone shape rather than all at once... so they call it inner and outer cervix). I've had a lot of friends have sweeps done, so I don't think it's that unusual in the States.
It is definitely easier to talk a doc into an induction here than the UK. I'm all for going into labor naturally (still really hoping I do), but I'm grateful to have a doc that is easily open to an induction as long as it's not too early. My hospital doesn't allow elective inductions before 39 weeks, so I think that's a really good thing. I've seen too many friends get induced at 37 weeks just because they didn't want to wait it out.
Ooh - and the weight thing! I'm up 34 pounds and at my last appointment I had gained 2 pounds in a week. My doc said "oh, your weight is up"... really?!
But much of my weight gain is all the water I'm retaining, so even though I *should* have only gained like 20 pounds, 35 pounds is still decent because I've retained so much water. Everyone is so different and I've seen people gain 60 pounds just to lose it all in a month or two. Don't let people's comments bother you!
