My last was 11 pounds, and I'm "due" today. I've also been induced in the past, so this is the furthest I've gone. I feel good because my midwife doesn't think this baby is going to break our record- but even if she did, remember that unless you're spilling sugar your body isn't going to make a baby you can't birth. I really really believe that.
Can you take a break from the cohosh and do something really settling for you? Massage, a bath, anything? I think less stress and relaxing will go further than the cohosh in preparing your body.
I know because I'm there with you that it is really hard to imagine that your body can and WILL do this. After being induced, especially multiple times, it feels as if your body just can't or won't, but it will- it really will.
I hope you get some time to unwind and relax. A watched pot doesn't boil, you know?
I understand though, I'm struggling with these same thoughts myself... I just got to see my midwife yesterday so I'm feeling mroe patient and relaxed. Love to you, mama!
