((Child why are you awake?
Well, you do need your sleep. But go into it understanding that you won’t get as much as you want. I haven’t been your age in a long time though (ten+ years… *shudders*) so I don’t remember how a body at that age is supposed to act on 4 hours of sleep.
But I do think you should go to sleep now. And have a nap after school (i assume it’s school). About an half an hour to an hour will do. As long as it ends before 6pm or so – if it’s after it’s too close to actual bed time and you’ll have trouble falling asleep the next night.
Drink ice water if you don’t drink coffee – it’ll help you stay a little bit awake. I hope this helps 🙂
