I dont understand what the big deal is about CC,you can adapt it how you wish.I think you have to sum up how much you want this to change and how much effort you are willing to put into achieving it.I dont support the CC regimé of leaving them to cry it out,unless you are very desperate and can support each other for 3 nights or so of "hell",very distressing,but it does work.However I prefer the CC regimé of returning to them,soothing them quietly with your voice and a comforting touch,and then leave the room.If you can repeat this,but leave it 1 minute longer each time,eventually they will tire themselves out and fall asleep.I think you have to set aside a week,withyour DP/DH full support,and say right this is going to be hell,we are going to get through this,but we will have little sleep for the next couple of nights,suggest starting it on a Friday night,because if you are lucky,you may have a good night by Sunday/Monday night.
The longer you leave it the worse it generally gets.Its now become such a habit,its very hard to "unlearn" a habit the older the child is,and they will resist at first.
You may be lucky lik the parent who's 2 yr old now sleeps through after Co-sleeping,but I think thats unusual if you read the other posts.
I really don't think babies over 6-9 mths need anything at night,IMO.They get enough calories etc during the day.Its a comfort thing,but they wont need the comfort when they learn to sleep through.
Now for the slating to start......
