Well, I was induced with my first DS, and I hesitated to reply here only because my experience was decidedly NOT that pleasant.
1. How does it compare to a natural labor if you've had both?
I was induced with my 1st child, and went into labor naturally with my second. IME, there really wasn't much difference, other than a slightly longer early labor phase, and the ability to move around and deal with the pain better when I went into labor naturally at home.
2. Were you diliated/effaced at all before the induction started?
I was barely dilated (a "fingertip"), barely effaced and baby still high. Looking back, I was a HIGHLY unfavorable candidate for induction... and I think my OB knew this, but didn't really care.
3. Did the induction work?
