Eh, I haven't gone through induction myself but a few of my mum friends have, one delivered her second baby through induction and she said it was faster than her first labour, maybe because her body "tahu dah" what to do. The experience really depends on the reason for induction and how your body responds, so I'd suggest asking your gynae about what to expect in your specific situation. Have you discussed with your doctor dah why they're recommending induction for your second baby?
