I did a dr. consult, and one of them had a serious infection, and the others were fine. But if the health is down and energy is up, sleep won't help. Take them outside, and give them little tasks, like pulling weeds or selling collectables, and they will get better. Vitamins didn't help me. Put the kids in the sandbox, and they will get better just a little bit faster. And let them take all the naps and eat all the food they want.
