baby is going to be big

Ashley
Ok I need a little help here, I don't have diabetes or blood pressure problems at all and my baby is weighing in at 8lb 3oz at 36weeks.. Just think I maybe a little further along then what they say cause I wasn't this big with my first 2 and they were pretty normal size.. I just need suggestions on how to start dilating which seems to be my problem and y I had to have 2 csection in the past.. I understand he will come when he is ready but I am literally in pain and cramp like crazy to the point to were I hit my knees when it happens..
