Doctor's answer:

At 3-5 a.m., it's the time when the lung meridian is active, and you've recently had a cold and fever. It's likely that there's a deficiency of yin that cannot nourish the lungs. You can try taking 6 grams each of peony root and licorice root, decocting them in water to drink. If you have time, you can also boil lilies, pears, and rock sugar in water to feed him, which can help nourish the lung yin. I hope my explanation is helpful to you.
