A lot of midwives have a payment plan option - pay some now, pay some on the way, pay the rest after the birth.
Sometimes it works out better not to have insurance, I reckon! We have been paying a premium for about 4 years now and it's been such a waste. All the money we spent on premiums is more than I would have paid for an op I had, for the osteo treatments I've had, the dental we've had...and still would have paid for a homebirth if we had put that money towards one! We'll cut our losses (because HBA might be bringing in HB cover at the end of the year) and pay for it without insurance cover, because all that we'll pay in premiums until I fall pg again (DS is really being an efficient contraceptive with his BFing habits!), not to mention the out of pockets we'll face anyway, will come to about what we'd have to pay for a homebirth. I just don't care anymore, I want my HB and I'll pay for a good midwife of choice when the time comes, even if I have to take out some kind of loan until the Baby Bonus is paid (those installment payments will suck big time!).
I was talking to a friend of my SIL's who had a HB, over the weekend, and I've got even more of a hankering now! So, someone have a word in DS's ear to stop feeding overnight...
