“I’m just not sure scientist’s understand hormones enough yet.”
Agree. Or the endocrine system.
The question arises. Does this merely remove symptoms, or does it block progression through a normal development stage in the child’s life that will burn them later?
I would think low dose melatonin for children who need it would not interfere with development, but I’m no doctor.
I suspect blue light might have a good deal with kids’ needing melatonin these days. I have known several young mothers in recent years who have to give their young children low doses to get them to sleep. These little kids were also spending time in front of screens in the evenings, and blue light from screens is known to interfere with the body’s natural production of melatonin in preparation for bedtime.

And young children spending too much time in front of screens does seem to affect development:
