@scottwilson I could understand how that would be frustrating.
I am fortunate that my kids seem to regulate their need to eat fairly well (or at least so far, my youngest is only 10). But our family culture may be a bit different than yours:
I married into an Italian family and they very much “live to eat” so if we visit them, there is definitely food to eat upon stepping in the door, lol. You have no chance to be hangry — bloated and overfed is definitely a possibility
though,
No but back to a serious note —
I am unusual compared to many households, and am lackadaisical about where the kids eat outside of dinner meal — meaning that as long as you pickup, you can eat where you want to be — bedrooms, your gaming desk, etc. so eating does not have to interrupt your desirable activity.
We also let our children graze as needed, from a very young age, so that may have helped them. I sort stopped tending to all their food needs in elementary.
What is your son doing like around breakfast and lunch time, that makes him not want to eat? Is this the only thing that he struggles with when it comes to executive functioning & motivation? How often does he need to eat from your standpoint. Would it be worth setting up text alarms to remind him to eat?
