So who is your perfect birth partner?

It gets thrown up in the news every so often doesn't it? Should fathers be at births or not?
For my first, there was no question. As far as I was concerned my husband had to be at the birth. He did well too and I'm glad he was there to help me with this strange new experience.
For the second, I gave him the option of not being there. I knew how traumatic it was for him. I knew what to expect, and that I could cope with what was to come.
Don't get me wrong. I did want him there but I realised that it should be his choice. I can't imagine what it's like to witness someone you love give birth. I can't watch strangers on the television! Without any drugs too!! No thanks ;)
Anyway, If you read my birth story you know that he did attend the birth of our second child, and was the PERFECT birth partner. I can't imagine giving birth without him.
It's his voice I hear through the pain. The one that coaches me and supports me. Just thinking about it makes me go all gooey.
