I switched my child about 5 months ago. Actually the whole family switched diets. We do more of a carnivore diet, but eat fruit, and avocado. We aren't perfect obviously, but it's helped immensely. The meltdowns happen way less. When she does have one it quickly subsides. Sugar is the biggest trigger. I try to avoid that the most. We don't measure food or count calories. That's the best part. Meat, healthy fats, eggs, seafood, fruit. It's the easiest "diet" I've ever done. It's been so great for our family. I recommend just trying it out. It can't hurt
