Sounds like you're making progress, LBH! With any luck, you're through the worst of it now. Do you know that solid sleep between the hours of 00.00 and 05.00 qualifies as sleeping through?!
You may find that while your DD stops waking for milk every hour or two, she will now wake early instead - I've read that CC rarely works once the baby's "up for the day" - 05.00+ - so you might have to resign yourself to early mornings. BUT if you can get to bed at a reasonable hour and you don't get interruptions through the night, I'm guessing that will still be a big improvement...
And you're not a shit mum - you're doing what you feel is best for you and your LO, which means you're a wonderful mum. She'll still love you as much as ever too 
Well, DD had an excellent night (for her) after two naps of only slightly over half an hour each, which didn't bode well. But in fact, she only woke twice between 19.30 and 07.30, took a feed both times then went back down without a fuss.
By my calculations, we're at Week 38 (corrected) which means we're through the first of the two developmental leaps that make up the 9 month sleep regression. And it hasn't been too bad, so far (she says cautiously, minding the MN jinx...) - the next leap is around Week 46, then that's it for a little while. We'll see how DD's sleep is once we're through that and then I'll assess whether any more sleep training is needed. Nap training, I suspect, will be essential if I'm to have any hope of her taking reasonable sieastas in her cot...
...and speaking of the MN jinx, there was I proudly describing how my DD was eating loads of puree etc. and WHAM, she'll hardly touch the stuff now. She seems to have decided it's got to be proper food only, a bit like chinook's DD. It's coincided with her getting all these new teeth, so I suspect she's finding it more interesting to chomp on things than suck them off a spoon. Luckily, puree can be spread on rice-cakes, so we won't be wasting it!
Good luck for tonight, LBH and everyone else who needs a sleep boost (almost all of us, I think...!)
