Hi Karen,
The word from the
Disney Dining Information is "Guests ages three to nine must order from a children’s menu where available." I know it can seem like the choices for children's meals are limited, but Walt Disney World has been trying to offer more choices for kids.
I looked at quick service menus and in addition to the turkey sandwiches, chicken nuggets, and power packs I found some great alternatives like Mickey Pasta with turkey marinara sauce at
Pizzafari in Animal Kingdom, a grilled vegetable sandwich at
Backlot Express in Disney's Hollywood Studios, and a great number of unusual choices at
Sunshine Seasons in Epcot.
Hopefully there will be plenty of Disney Dining options your kids will enjoy!
Wishing you and your family a magical vacation,
Amy H
