DD sleeps unbelievably deeply, has done since primary school age. Trying to rouse her is a massive effort every day; I feel like a nurse in theatre recovery. When she does wake she is usually incoherent for a few minutes, still talking as though in a dream. Left unattended she will also fall deeply asleep in the afternoon. We try to prevent this so that she gets better quality of sleep overnight. It's causing a lot of stress around getting her to school on time, and getting her to take responsibility for her own routines. She's in year 10.
Does this sound like a medical condition? Or a mental health issue? Or neither, just something we have to live with? I want to help her but don't know where to turn.
