Autistic child + hunger trigger

[Mummyrobot]

My son (9 yo) has received an autism diagnosis over the summer holidays and we are preparing for back to school chat with his school about adjustments that need making to help him come September.

We've noticed that nearly all his meltdowns and shutdowns happen when he's hungry/due a meal/skipped a snack. We want to ask that school make sure he eats properly at lunch times, but also send in some snacks for emergencies during the day. Ideally I want packaged things because there's no way of knowing what quantity he needs day-to-day but don't want to packing him full of sugary treats. Any suggestions? He won't eat cheese and nuts are out because school is nut-free.

Also, anyone else with autistic children who have similar hunger trigger, I'd love to hear any tips for how you manage.

Thanks!

My son is like this. We send him with a snack box each day which usually includes crisps/oatcakes/cheese thins/Ritz crackers or some type of savoury carb. Pepperami or cocktail sausages. Carrot batons, cucumber slices, grapes or strawberries and sometimes chocolate cake slices, Oreo cookies or chocolate chip cookies as a treat.

Protein rich breakfast also help.

So poached eggs on toast. Or scrambled eggs and baked beans. Tinned fish, etc

Food is a massive trigger for my youngest to the point he's under specialist consultant care for the food meltdowns ( evening going past a food outlet/ supermarket can trigger a meltdown of epic proportions) his school is fantastic with this and ensures he has regular food breaks, always eats his lunch and he gets to do baking once a month with the senco one to one. I appreciate I'm really lucky with the school he attends and he gets lots of support. Wish you the best of luck moving forward x
