I preferred my first birth, I found my second more painful. He was only born a week ago :) anyway...
DS1 was induced using pessary, I laboured for 24 hours, had tens at the beginning, then dia-morphine, and gas and air which was stopped at the pushing part, I found biting down on the mouthpiece great though. No tears just grazes.
2nd DS, I was in slow labour for 5 days, contractions every 10 minutes with very little affect on cervix, couldn't sleep as was too painful, then on the friday at 5.20pm I got a super strong contractions that where coming every couple of minutes lasting about a minute, this happened until 6.30pm when I decided I needed to go to hospital (kept telling myself I'm coming home as its just another false alarm)...got checked at 7.30pm and was 3-4cm dilated, so could still stop, I walked and walked all the way round the hospital, to be checked again at 11.30pm and only be 5cm, but was then told that baby is laid funny, he's on his side but more back to back which was making me unable to progress well and making the pain excruciating, he was unable to move down enough to press on cervix and there was a gap so was threatened with cord prolapse if waters went.
I was finally ready to push at around 4am,waters hadn't gone, baby hadn't moved, I pushed with every contraction to move him round and was 1 more push away from having to have forceps and vacuum,I gave one good very painful push and I managed to turn him, after 1 and half hours of pushing he was born. I had gas and air, paracetamol and dia-morphine during this labour,overall time was 10hours.
I recommend dia-morphine, it really is a life saver!!
Good luck
