She was only 11, but her mom knew something was terribly wrong

You've had a bad feeling all summer, a nagging in your gut that something's wrong. She looks thinner, but she just turned 11 and kids that age get taller, thin out. Yet ... why is she so pale in July? Why is she tired all the time? Your husband said it was because she'd been staying up too late on her iPad, so you limited her screen time. That didn't help. She keeps falling asleep smack in the middle of bright summer days.
