Hi im new to this hopefully someone will have some advice. My lo is just 6 months old and since he was born most nights have been horrific with getting him to sleep. I have frequently slept on the sofa downstairs with him in his carrycot as he just will not go upstairs. most nights I only get 3 hrs broken sleep and im at the end of my fuse. He will cry (more like a blood curdling scream) for over 3 hrs at a time even when being comforted. I have made sure he isnt hungry have a temperature or need changing and done all the usual things but nothing makes a difference and I dont know what to do now. He is so tired now he just screams and I dont think he can even stop himself or even really knows why he is doing it. Any advice would be greatly appreciated we are both really suffering.
