My DS1 wakes up every day sometime between 5 and 6am and has done for the past 2 years. He goes out like a light when he goes to be at 7pm. My Mum says that when he starts school in Sept, it'll change as he'll need more sleep and find it exhausting. Other people have told me the same, so I'm clinging on to this at the moment. He attends day care nursery for 3 full days a week, so used to long days. Does this really happen?
