My son (24M) has food issues that are frustrating. He is nonverbal and communicates by gestures mostly.
He tends to use apps on an iPhone also but limited. He does not have food aversions but prefers tenders and nuggets. The problem is he asks for meals like he’s starving. When meal is provided he just lets it sit there. He will repeat this until the mountain of food is at a ridiculous level. He piles bags of chips and cookies on several plates also. Eventually he will sit and start eating he doesn’t finish it all but gets mad if we want to throw it away at the end of the day. He does the same with drinks. Has about 5 glasses of various beverages that go to waste because he only drinks about half of one glass. He lines up the empty bottles and cans until there’s no more space to place them on the table. When we go out to eat he’ll grab food from other people’s plates to pile up on top of his. He also waits to eat until we get back home to start his usual routine of piling up the food. He doesn’t pile up anything else except his fidget toys that mostly consists of Lego pieces. They have to be tiny and colorful. Doctors have tried different meds to help with OCD ADHD ETC but alas here we are still.
