I am just seeing this now but I thought I'd chime in...
Do I regret her being there as my support person for my first birth? No. Do I regret her being there as my ONLY support person... 1000 times yes. My birth would have been much different if I had someone to actually listen to what I wasn't
saying (any of my three closest friends, although I wasn't close enough with one of them at the time to ask her and their were other factors preventing the other two from being there at the time). She was too busy being a nurse to do that when the going got rough.
Do I regret her being there for my second birth... yes. If I had known that I wasn't going to hit four centimeters and just be done in an hour like I was the first time I would not have called her when I did (as it was I stalled at four and then my body kicked into gear a few hours later and I went from still four to baby out in 15 minutes *can we say intense?*
). I knew I didn't need her there, I just wanted her to see the baby be born and she ended up doing what she always does and making it about her and taking over... she didn't mean to but she's really upset me about some of the things she said at the time and has said since.
I doubt she'll be there *while* I am birthing ever again if there are more babies that come through me. Immediately afterwords though? Yeah, that I knew I would want her there for (and did). She has been absolutely fabulous at taking care of me so I could take care of my baby both times.
