Quite the contrary. It’s abusive to only feed your kids mcdonalds, because that’s the only thing they want. You’re telling someone who doesn’t have the nerological capacities you do that they can decide whatever they want to eat.

My kids get a varied diet with all the nutrients they need. They can choose not to eat it, that’s fine, but I’m not going to give them mcdonalds instead. Mcdonalds does not provide the same nutrients as a well balanced meal.

Sometimes I persuade them to “just eat a few bites” and than they can have desert as reward.

Maybe this approach doesn’t work for neurodivergent kids, but I never claimed it did. If you have a neurodivergent kid, you should maybe look into other methods. I should add that I also don’t know if this works for children of all ages, genders, races, handicaps, species, planets and dimensions. It works good enough for my kids and I’m taking that as a win.
