Gas & air was great - was cut off for about 10 mins at 10cms as had to move rooms and it was torture!
Couldn't have done it without DH there either - didn't expect to say that!
And as above - the odd shout/cry/moan through the pain helped and I hated feeling that it was frowned upon by the midwives.
Staying at home for as long as possible as well. Had got to agony stage when we left for hospital and only in hospital then for about 4 hours before started pushing.
But no other tips - nothing I could have brought with me or did before helped. Didn't want flannels or food or drinks (with packed straws!) or pre-prepared music on my ipod and doing yoga etc made no difference.
