Soyabean, if you want to avoid epi, try to avoid induction, avoid going to hospital early (may not be possible if waterbag prematurely ruptures or if you have strep B infection which requires IV antibiotics during labour, or any other condition which requires monitoring from early stage of labour). Cos if you request for epi when you are more than 6cm, the doctor won't give it to you cos too late. So you are "forced" to go without epi. If your bb is in a good labour position (not bb's spine against your spine) and if you keep moving constantly (stay upright, change positions, walk, climb stairs during early labour), chances are you will be at least 4cm dilated if you experience contractions lasting 1 min 5 min apart, for 1 hour. Once you are at least 4cm, and if no change to bb's position in the uterus, you should be dilating at at least 1cm per hour. Once you are at 7cm, you are at transition stage.. the toughest stage. you need to be in hospital by 7cm. So between 4cm to 7cm, you have about 2 to 3 hours to pack up and go to hospital. Hope this info helps. I'm hoping to go without epi too.. but taking it step by step. Just want my bb to engage first... then confirm I dun have Strep B.. then see how it goes!
