At the very least, you know, parents should check into restaurants and see what the menu looks like, see if they even serve food their children would personally eat. While we were on vacation, we went to a 'fine dining' restaurant (I use that term loosely, based on the area) by mistake. They had a kid's menu, but it was very limited, kind of tacked on the end like an afterthought. Nothing Alex eats, had I known, I would have stayed away. That should hold some weight in terms of decision making..I paid a significant amount of money for Alex to eat bread and sip water.
For me, that screams waste of time and money. Even though Alex was very agreeable and not disruptive to others, that is still way too much hassle for no valid reason. Not to mention, I wasn't about to make sure I was full and not worry about Alex. That just involved an extra stop on the way back to the hotel..finding Alex a child-friendly meal. Because we inadvertently stopped somewhere too fancy for him, I had to pay for him to eat twice. Which wasn't a big deal, but..you get what I'm saying. Sometimes, it's not even worth it anyway..
You can fight too heavily for your parental rights for no reason. If your kid wouldn't eat the food, you don't really need to take them. Just saying, personal experience. Because if there is nothing on the menu that appeals to your kid, that's more likely to cause them to fuss..and even if your child doesn't normally act out, being hungry in a restaurant that does not cater to his/her appetite, might just be the final straw..
