It is a dodgy time for sleep. When DS was the same age he did the following;
5.5 mts - crawling backwards
6.5 - crawling forwards
7 - pulling up
7.5 cruising
After that 6.5 - 7.5 month was up he slept well until he was 13 months where he got a little bit dodgy. Not his fault that time though, me moved in with the outlaws and my FIL was disturbing him. Anyway... enough about my DS!
The hourly wake ups is a typical response to a negative sleep association. Not all kids are negatively affected by feeding to sleep but it appears that your DD can't self sooth hence the assistance required throughout the night. It can be a bit more of a killer when the developmental leaps are in play as they will often want a middle of the night party (MOTN as I used to say)
How do you feel about pick up, put down as a technique for teaching her to self soothe? Here's a guide www.mybabysleepguide.com/2009/01/pupd-tbw.html
You're not leaving her to cry, but she may cry in the process. It is age appropriate.
I always like to point out overtiredness as I believe that sleep = more sleep. Here's a guide to awake time lengths in the daytime www.mybabysleepguide.com/2009/02/wake-time.html
I think with a BF to sleep assocation you need to use your best asset - your DP. He doesn't have what she wants so without you, she can learn how to fall asleep without thinking, 'hey, mamma - you've got what I want, why aren't you giving up the goods?'
Your routine needs to remove the feeding to sleep element altogether. DS has had the sleep routine of bath (if needed), PJs, milk downstairs, teeth brushing, book x 3 (always the same ones) and then bed. He goes in wide awake and has done since about 4 months.
Re milk at nighttime, I think you need to set limits. I personally believe that at 7 months that there is no requirement for milk for at least 7/8 hours and by 9 months they can do 12 hours. I'd do a feed in the bedtime routine, a dream feed and then nothing until morning. I think 6.30am is often fair.
I hope this helps!
