Birth Partner

[kelebek]

ok so my sister is due in Feb 2012 it will be her third child but her other two are 9+ yrs old so it is has been awhile. She will be not quite 31 and I might get to be one of her birth supports

She is getting a copy of the calmbirth book but I am just wondering what sort of things should I be thinking/doing about for her? how do I make sure I respect her wishes?
she is not quite the 'hippy' that I am she trusts her dr's but she did have traumatic births the first 2 times. She thought she was over them but I think now she has the u/s and is past the magical first trimester she is starting to process them again... any suggestions on how to help?

thanks for now and I am sure I will be back
