I have only had one labour but the biggest bit advice I could offer would be to move move move move.. I had a text book labour (according to mw) but it went on for 18 hours. I am sure if I just got off the bed and walked it might have been shorter.. and to remember yes it hurts but not to be afraid of it. in my opinion it hurts more to kick your toe well not really but kicking your toe is a sudden pain and labour slowly builds up kwim?

Just relax as much as possible and don't tense up
