As a parent, I totally agree with you & can't understand why some parents don't seem to get that. IMHO, it's extremely rude to allow a child to negatively impact another's meal. When we have children they become our responsibilty. The only people who should have their meal interrupted by a child should be that child's parents.
To the OP, all WDW restaurants are kid friendly for the most part. The fact that you thought to ask this question probably means you're sensitive to other's feelings. That will be very much appreciated by those dining around your family. Enjoy your trip!
