My 13 month old DS sleeps as badly as any i have heard of (sleeps lightly, wakes frequently, cries furiously, won't be soothed by anything). Just gets worse and worse and i'm beginning to wonder if there could be something physical wrong, rather than the usual psychological explanations (attachment, separation anxiety etc) none of which quite seem to fit. Even if it was something incurable, it would be so good to feel i understood what was going on.
Does anyone know of any such condition?
