3yo usually a good sleeper but every so often has a full night of being awake, shouting and screaming (I want to go outside, I want to go downstairs, I want breakfast). Wakes up in the morning, miserable and shouty again. Doesn't want to go to nursery which he loves. Just utterly miserable for 12 hours. I guess this is normal but I'm a lone parent and working today and can barely keep my eyes open/feel nauseous/shakey because I've had approximately 2 hours sleep. No idea how my child has so much energy this morning. Close to tears I'm so stressed.
