my 10 month old was doing exactly the same up until last week - sleeping from 7pm til 10.30pm, then waking for a feed (which I did, because I was just so knackered & couldnt face doing anything else) then waking every 2 hours after that thru the night. She was just latching on, the lying there, not even bothering to suck because she just wanted me as a comfort, not to feed.
Last week I snapped though, & couldnt take it anymore. I figured if I could get her back off to sleep after the 10.30pm wake-up WITHOUT feeding her, then it might help things... so that's what I did.
I started last Wednesday night, she woke (like clockwork) at 10.30pm, and it took me until 11.30pm to get her back off (sitting by cot & patting / stroking / shushing her, a couple of pick-ups & cuddles, but that seemed to piss her off even more because she thought she was going to get a feed,so i suggest not taking her out of cot if you can help it!). She then slept til 4am when I bf her, and she went down fine til morning.
Thurs & fri night it only took 45mins to get her back off at 10.30pm without the BF but with patting / stroking her tummy etc - both times she slept through til 4am, when I was happy to BF her at that hour.
Sat night she rallied & it took me til 1am to get her back off...arghhh! But sunday night she was fab and slept through from 7pm til 4am!! Last night she went 7pm-2am, when I fed her, then she slept til 6am. I know I need to drop the 2am (or 4am, or whatever time feed!) she wakes for, but at least now I'm only bf her once at night, which is MUCH more manageable.
Hope that helps - stick with it, it'll feel tough trying to get baby back to sleep without the feed, and she will inevitably cry because she's annoyed with you that she's not getting a BF. But she WILL go back off eventually, and it should only take a few nights of pain to make the gain! I am planning on dropping the early hours feed once baby is regularly doing 7pm - 3am (or whatever time in the morning she wakes). I won't, however, feed her if she wakes any earlier than 2am - she will be patted / shushed back to sleep if she wakes before then, 2am is the cut-off for me!
Good luck - you'll get there I promise!
