Dd, 8, really struggles to get to sleep. She has the usual routine of supper, story, sleep, but often it takes her hours and then she's a crying mess in the morning. Last night it was 11 when she finally nodded off. She'd gone to bed at 8! She says when she gets in bed she's tired but her body just doesn't let her sleep. She's not an anxious child, and she gets plenty of exercise. It's like she's just a night owl, but that doesn't work for school days does it? Has anyone found anything to help?
