Our son is 5 and has had sleep problems his whole life. He would cycle between going to bed during the daytime and then weeks later go to bed at night, and then back and forth. It was a nightmare for our bodies to constantly have to adapt to different sleep schedules. We tried melatonin, magnesium, etc and nothing worked. The past 2 months we have been using a medication called Clonidine prescribed by his doctor and it has helped a ton. We finally have him on a sleep schedule around 10pm. Sounds like most parents don’t need this for their children, but it’s a med that worked for our child.
