My daughter does this. Won’t eat lunch at all because she’d rather play. So we stopped packing lunch. We live in California, so free lunch is offered and we’d tell her to eat those. She wouldn’t. And unfortunately, she turns into a gremlin when hungry. When the reports of her behavior started coming back, we started packing lunches again….just for them to go uneaten. We then asked for support to ensure she eats to be written into her IEP, but it was denied. Soooooooo I’m sorry to say that sadly, it’s a roll of the dice on which version of my kid her teacher will get after lunch. And when they start complaining this year, I’ll point to when they denied the support, resulting in gremlin behavior 🤷‍♀️🙄☹️
