I also did do controlled crying and found that it worked over time, but that is more relevant for when they don't settle when you put them to bed - it's the last thing you want to do in the middle of the night !

If you do get to the point where you are just going to do CIO, maybe try some earplugs! LOL!  Good luck - I hope the sleep fairy watches over you tonight!

If he's waking up to feed, could you maybe try reducing the amount you give him so that he eventually gets out of the habit of waking - or giving him water for that feed?  I know some babies need more than others so not saying you should do it, but if you feel that he really doesn't need that feed, maybe see how you go with it.  I dunno - just a bit of giving everything a go to see what works.  Something has to eventually aye?

Annie you poor thing.  I have just had dejavu though.  We had the same thing for a couple of months and because my partner could sleep through an earthquake, typhoon and tsunami, it was down to me to get up all through the night (which, trust me, he copped ear bashings over it on a daily basis).  I work full time, so was a walking zombie surviving on about 4 hours a night.  I put it down to bits and pieces of everything - teething, cold, packing up house, moving house, new house - but it started way before we moved and carried on way after we moved.  Then she started performing when we put her to bed each night as well as during the night. 

Hmm, what did I do?  I bought a little CD player and a lullaby CD and played that when we put her to bed.  Then for the night wakings, I put a mattress down on the floor in Gabrielle's room and got a blanket and slept there most of the time.  Every time she woke up, I would just "shh-shh" and "mummy's here" without getting her out of her bed or even looking at her.  Oh, also put a night light in her room.  It then started to peter out and after about a week or so of that, she stopped waking - well not so regularly anyway.

The only time she has backtracked is if she is sick and I would take her to the spare bed and sleep there with her.  She's in her own bed now, so if she wakes up upset, I just climb into bed with her and go back to sleep.

To be honest lovey, you just have to do what you can to get some sleep.  If it means doing what all the text books say not to do, don't worry about it.  Your household doesn't function without you, so you need to be given some space to recuperate, and that is going to take help from Rod.  All the best - I really hope things are on the up.  Things seem a million times worse when you're sleep deprived.
