I just read this, so would say no until after you’ve talked to your child’s pediatrician. “Melatonin is a natural hormone and long term in young people can affect their growth hormone. I would be more interested in exploring his diet, bedtime routines, parental response to his sleep issues, medications, tonsils and adenoids, etc to see if we can determine a cause for his sleep issues and address that.”
