When I had my daughter 6 years ago, I considered an at home birth, after some thought, being it was my first we decided against it.
I had a text book delivery with my daughter, it could not have gone better, in fact I used to tell people that it was such a cinch I could have ten more!
When I got pregnant with my son, again I considered it...and for whatever reason (thank God) we chose not to. I had 2 Postpartum hemmorages. Passing clots the size of softballs! I had 2 emergancy D+C's and blood transfussion. I developed an anxiety disorder as a result of this, and almost a year later am starting to feel better, but will be on anti-depressants for awhile yet.
What happened to me is rare, but it does happen, and i am just grateful that I was in the hospital and not at home when I had all the complications.
So whenever I hear of anyone considering at home births, I cringe.
Good luck in making your decision, and with your delivery!
