Thanks girls, my sister did so well, she had a bit of pethadine and a tiny bit of gas and air as it made her feel sick.
There was a very surille(sp) moment, she found it nice to sit on the toilet, so she was on there a couple of hours and when she was having contractions she liked to be left alone, so she was having contractions and i was on the side of the bath eating hob nops!
Also her hubby ended up staying through the whole birth and was very supportive
