S.S.
I used a Doula, Linda Cameron, with both of my babies - Cole was a 24 hour induced labor @42w6d, who was followed by a c-section because the baby stayed at a -3 - when he went into distress, I found the decision made for me. Jason ended up being a planned c-section. The first time, Linda was a perfect birth coach. The second, she was an amazing babysitter for my 2 year old.
With Jason, originally, I wanted to use a midwife - but the insurance didn't cover it, and their fee wouldn't count towards the deductible if I ended up needing a physician. There is, however, a birthing center or two located in Dallas - they are close to the hospitals and partnered with 'real' OBGYNs if you need a doctor at any point. That would likely make your husband feel much better about the idea of 'not using a doctor'. On the other hand, if your 12 year old and 17mth old were both 'easy' deliveries - maybe meeting with a midwife who does home births would put your husband's mind at ease.
