I am exhausted and survive on 3-4 hrs sleep a night, which is poor quality sleep as it is proped on my side with my toddler latched on.
Dh is great with him, but has had enough and has started to suggest I wean him. He is hoping for a miracle to happen, if ds isn't breastfeeding any more. Due to often spending hrs in the evening with ds screaming, he isn't keen to help more during the night as well. He is already exhausted as it is and I can't sleep with ds screaming for me anyway.
Work is respite (I'm a youth worker), but I drive home feeling tense, knowing I will open the door to ds screaming for me and dh feeling pissed off and hard done by that he has had to put up with it while I was out.
My other dc are 3 (shares a room with ds and still wakes up 2 to 3 times a night), 14, 16 and 18. Until recently the oldest 2 were doing exams, so it would have been unfair to leave ds screaming in the night.
Daytime feeds now seem to last until I get fed up and take ds off. In response to me restricting it during the day he now just hangs onto it for dear life when he does get it. He won't take more than a sip of anything else. I would of thought he would be eating more out of hunger now, and drinking other things due to thirst and the recent heat, but no.
Don't want to wean ds off the breast, just have a more resonable feeding pattern. Beginning to wonder if that is possible with him though and I will have to except things as they are or wean him off. 
Sorry for the long rant. Feeling sorry for myself at the moment.
