She sounds very like Mira

Mira gets so distressed, rubs her ears, cries and cries like she's in total agony, won't settle for anyone but me. We tried DH giving her a bottle, she took a full 5oz, then screamed for me to get her to sleep. If I give her a bottle through the night she takes an ounce if that, so it's definitely me she wants not the milk

I really want to take Mira for cranial osteopathy as I've heard good things about that and sleep problems, but we just can't afford it. If we didn't co-sleep I'd have gone nuts with how many times she wakes up and it's never made any difference whether she goes to sleep with or without boob. The only thing that makes a slight difference is her falling asleep actually in bed and not on the boob in the living room. We're talking about the difference between her waking 2 hours later though instead of 30 minutes, so not a massive difference. Most nights she wakes at 11pm, 1-2am, 4am and then 6am, 7am and we get up at 8. And that's a good night! I had hoped to not night wean her, which I did with Kacie at 14 months because I was pregnant, but I can't cope with another year like this so I'm going to do a version of Dr. Jay Gordens method
http://drjaygordon.com/attachment/sleeppattern.html but for just a 5 hour stretch not 7 hours. I'm pretty sure at almost 12 months she can survive 5 hours without milk overnight and if I do it between 11 and 4 and go to bed then at least I'm getting a reasonable stretch.
The problem is in the first 12 months there's just one thing after another as to why they have bad nights. If it's not a growth spurt it's teething, if it's not teething it a bug they're fighting, if they're not fighting something off they're having a developmental leap, and so you go round in circles. The Wonder Weeks is a great book and website for explaining some of this
http://www.thewonderweeks.com/index.php?option=com_content&view=article&id=120&Itemid=236 I always find it easier to cope with the constant wakings when I know there's a reason. I started co-sleeping with Kace at 9 months for this reason, side-carring the cot so we both still had our own space, but it was so much easier to just wriggle too her, feed her and then wriggle back. Plus when you're in your own space like that you don't disturb each other moving around the same.
Not sure if any of that helps Sadie, but just know you're not alone

I've got friends who've both breast and formula fed their little ones who've had bad sleepers. Unfortunately when they're so young they can't explain what's wrong so we just have to comfort them as best we can.
