Can't cope anymore. He's 21mo, has been in some sort of sleep regression for over a month. The past week in particular I've been getting snatches of an hour at a time, and now he has a cold so it's even worse. He won't respond to sleep training the way he has in the past. Nothing seems to work. I can't cope with being screamed at and hit all day because he's so tired, and then screamed at all night because he won't sleep. I'm so tired. I wish someone would take him away from me just for a while, so I could sleep and feel strong enough to deal with him.
