Hi Natalie, that is so great! I was my sisters birthing partner when she had her second baby 3.5 years ago (hospital birth) and her 3rd baby 2 years ago (homebirth). it made me think about doing midwifery and now I have a place at CCCU for Sep09. Last October I was birthing partner for my other sister (hospital birth, her first baby). It is so lovely to be there and support her and enjoy the birth. I found that the blokes tend to be a bit in awe of what is happening so I got to be quite proactive for my sisters, requesting things (birthing ball) and suggesting things that the guys could do to help.
Good luck :o)
