All of my births have been at home. My first was VERY over- and mis-managed, and there was a lot of conflict with the midwife. It was also long and I had no idea how to deal with a long labor -- basically I just sat around obsessing about how far apart the contractions were, feeling annoyed, until it got hard, at which point I was
mad. It was a difficult and traumatic birth with a long recovery time and severe pospartum depression.
My second was very healing and empowering, I had found a midwife sympathetic to the way I wanted to do things, and I approached the labor with a much better attitude. No obsessing, no measuring, just acceptance and trust. Most of the first part of it I labored alone, and felt really good. Then my midwife showed up and it all kind of went to hell -- not because of anything she did, but just because she was sitting there
watching me and I lost my concentration and got self-conscious. So then again the labor got really hard, although compared to the first birth it was nothing, and the baby was born relatively quick and easily.
So the next time I was determined not to let anything interfere with the natural process, and planned to give birth unassisted, though I wanted to remain flexible about my needs, so I had two midwife friends on-call. It was again a long labor, and unfortunately my husband wasn't there as much as I wanted him to be (work-related stuff,) he would have if I'd asked but I was playing the martyr. Like, "I'm tough and strong, I don't need anybody's help!" Which was stupid because I really wanted some attention and love, and when it wasn't there my attitude began to deteriorate. It dragged on and on and I got bored and started to obsess like I had with the first birth, against my better judgement. It just kept creeping back. Finally my husband was back, the kids were asleep, and everything was ticking along as it felt like it should be (I think I was close to transition, and doing VERY well,) and what should happen but my MIL SHOWS UP! My husband didn't know what to do, he was waiting for me to give instructions, but I couldn't do it. All I could do was smile and say "good" when my MIL asked how I was doing. So with the intrusion the labor (just like with my second) suddenly became very difficult and painful. My MIL finally got a clue and left the room, and not long after the baby was born. Then my MIL COMES BACK IN, laughing and crying. I was SO pissed. This was a time that was meant for us, for just me and the baby and my husband, and it was lost in having to acknowledge the presence of someone who wasn't supposed to be there.
Well, you can guess where this is going. This time there will be a sign on the door, and my husband will know not to let anyone in! I also plan to have people around (our friends who live across the street, and possibly a midwife friend to stay with them) to hang out with if I so desire, and family members to take care of our kids (if it's during the day) so I can have private time with my husband so he can, um, help me get the oxytocin flowing.

I am really looking forward to it!
