Must they be inside a theme park? If not, and she needs to use her TS credits try:
The Wave at the Contemporary (although this may have caught on)
Turf Club at Saratoga Springs
Olivia's at Old Key West
Sanaa at Animal Kingdom Villas
Maya Grill at Coronado Springs
Shutters at Caribbean Beach
Captain's Grille at Yacht Club
Wolfgang Puck Cafe, Planet Hollywood, Raglan Road or Cap'n Jack's at Downtown Disney
These are not mentioned with regard to what they serve, how the food is or their level of child-friendliness - just that they do not seem to be in as much demand as other restaurants (that is usually due to location) and might have space if everything else is full for
free dining.
If she does not have a car it will take time to get to any of these restaurants (except the Wave if you're at MK or Captain's Grill from Epcot or Studios) via Disney transportation either from theme parks or from other resorts.
