With my first I went with no intentions, I just thought I will see how I go. I laboured in the pool with just gas & air and I found it fine! I had to get out the pool after an hour of pushing and they found my son had pooed inside. They let me push for one more hour on the consultant led ward but still only g&a. Unfortunately he got stuck so they took me to theatre and prepped me for section but managed to turn him round with forceps and I pushed him out then
This time round I still want water and gas & air but will be going in again with no expectations as I don't want to be disappointed if I don't get my perfect birth.
At the end of the day however my baby gets here and whatever pain relief I need is just minor detail in the grand scheme of things.
