That noisy cafeteria vibe can definitely throw off a kid’s appetite - my nephew went through something similar when he switched schools. Have you thought about packing foods that are easy to nibble on quietly and don’t require sitting still for long? Things like mini wraps, cheese cubes, or even a thermos with a warm soup might feel less overwhelming than a full sandwich and veggies spread out on a tray. Also, maybe giving him permission to eat parts of his lunch at different times or even outside the cafeteria (if the school allows) could help. Sometimes just a change of scenery or a quieter corner makes a big difference. It’s great you visited the cafeteria together - that kind of support means a lot, even if it doesn’t fix things overnight.
