Grrrrr third time of typing this as bloody phone keeps telling me that internet has stopped and eating my posts!
Great that you got a third nap in today Zombie. I dont think it's bad that you let your mum take DS for the night, you'll be much better able to parent if you are well rested. Same reason I packed DH off to the spare room tonight so he can get a good rest and take the pressure off me tomorrow.
Glad you had an ok night in the end RP, some real positives in there and you have made some great progress. Hope tonight is even better.
Thanks for the offer of an osteo recommendation, I actually live in Bucks so not exactly just down the road!
The lady I will go to was the one who treated SIL's little boy and comes highly recommended. If nothing else DD should get a lovely relaxing treatment 
Oh and I am BF still, we dabbled with formula at last feed for the past week but since hunger doesn't seem to really be the issue with DD's wakes am now back to ebf.
First real wake-up after 3 hours and feeling surprisingly upbeat for a change. Positives are that I neeeeearly managed to settle DD in cot without feeding (so close!) making me feel like there might actually be a time when I can. Ended up feeding as she got upset but that's ok. Fed her briefly but she kept crying when taken off the boob then when I put her back in her cot (just to see what would happen) she settled instantly
next time will try doing that a bit sooner.
May the sleep gods be with you all!
