Our three-year-old wakes up at about 4:30 every morning full of life and won?t go back to sleep. During the day he expires just before or just after pre-school and wakes up in a really grumpy mood. We then have a struggle getting him to sleep at his usual time of 7:30pm as he is wide awake again. But no matter how late he stays up he nearly always wakes up again pre-dawn.
Can anyone offer some advice please?
