Hi
Oh i really feel for you.... i had that problem for a very long time .. we tried so many things and in the end I was so excausted I could barely function.
I do believe after coming out of the other end at about 18mths that they are creatures of habit and the habit of waking up has to be broken ! I found it very hard to do CC so tried lots of different things.. and it seemed that as soon as we got some progress he would get sick and we were back to square 1.
People used to say to me "it will get better" and i felt like screaming at them !
Hang in there... its a tough gig having a baby that does not sleep. I found that once i got the day sleeps a bit better sorted I was a little more able (less tired) to work on the night ones.
Probably not much help but you are not alone.. I ended up going to Torrens House in Adelaide to get some help not sure if you have anything like that where you live ?
