Epidural for induced labour

I was 3cm for both pregnancy and I was only induced for my first pregnancy but not the second. I took jab, gas and epidural after few hours in labour when I am not dilating. Mind you for first pregnancy (most of the time) and for induced, labour can be pretty long and dilation to take place would be on average every 1cm opening will be about 1 to 2 hrs. If this is second pregnancy can be pretty fast but depend on the body. I took my second pregnancy gas and epidural. But the moment I just about to have epidural, my dilation was 4cm to 10cm within seconds. So you have to really prep yourself. If you think pain tolerance level not high, dilation takes pretty long then take it and rest. You need energy. But be prepare for side effects upon taking epidural. Also when taking epidural may/may not work for certain mummies so always be prepared for other birth plan method in mind.
