I hear you momma. My daughter goes in and out of this too. When she is extra and easily melts down. We turn all screens off in the house. Play only Lofi music or piano then look at what she has been eating. It’s their gut that is running the show so see if you can get some probiotics in him someday. Shoot. Even that new soda Ollipop could work. Start cutting out anything with added sugar over 5g and direct him towards savory stuff or fruit. There will be resistance so make sure you got a little rest before making this shift. Because you will need your “no pushover” pants on lol.
It’s a phase; my daughter this week I’ve noticed is being super picky with food
