i think you you have a lot of great responses here but i would like to add that i was in a similar position you are in. no one i knew had a homebirth but i came across a book on it at the library and felt like it was right for me.
i had a lot of support from my DP and also a lot of trust in my midwife. what i liked too, was that she came to me even after DS was born. i would definitely have a homebirth again. good luck to you!
