Haha, I'm so glad the gum worked! I am not a big mint fan either, but it makes everything so much less appetizing. Just try drinking orange juice with mint in your mouth and not cringe
Good luck with their picky eating! At least in this house, I tend to offer more 'fun food' main courses, like sausage, Mac n' cheese, burritos, cheese spread, etc etc, from healthy recipes, and then make sure the side dishes are fruit and veggies (usually stuff like peas, pineapple, carrots, prunes, etc etc). The rule in our home is that you have to try one bite of your main course and finish the fruit and veggies. The servings are small, maybe a tablespoon of each at a time, and you cannot have seconds of the main dish without having first eaten all the produce components. It's little enough food and tasty enough choices that even my pickiest eater complies a good 80% of the time. The other 20% she chooses to go hungry and be re-served the food every meal until she eats it
That doesn't work with all kids, especially those with texture issues, but it is amazing what those little recipe substitutes can do to retrain their palates. Slowly but surely changing them is right on, I wish you the very best in BOTH endeavors
