My 2 1/2 year old son used to happily go to bed, he'd sing at the top of his voice to get himself to sleep and the same again til we went in in the morning. He's had a sickness bug followed by chicken pox, during which we slept in his room a lot, and now, even though his health is better, he absolutely cannot fall asleep on his own. One of us has to sit by him til he sleeps, he gets incredibly distressed if we try to leave him, and he's waking at least once a night, usually more, where we have to do the same otherwise he doesn't go back to sleep. We've tried a bit of leaving him, but he stands by his door and wails himself into an awful state. If we leave the door unlocked he just comes into our room again and again and again until we give in and sit with him. Net result is he's knackered, not sleeping nearly enough at night. Does anyone know if this is normal post illness, and if so how long it tends to last? Or if not any tips and techniques to help him return to normal form? As well as exhausting him, it's making me really depressed, I get very frustrated with him and want to scream. I don't, but I'm really tired and not sure how much longer I can bear it
