Hi V.
She could be just getting bored with baby food. You might try some actual food,(not just cereal), anything she can hold in her hands. Cherios, Graham cackers, rice cakes (they come in many flavors, cheese, apple) anything that she can hold in her hand, and gum and disolve easily. Yogurt(let her use the spoon, she and the high chair will clean up afterwards), mix some cereal in with the yogurt or cottage cheese, cheesce slices,canned or frozed veggies (peas and carrots). She can eat these things with her fingers. Let her taste what everyone else is eating for dinner, just give her very small bite and cut it up well or use food processor. Meatloaf, scambled eggs, some cream pie for desert, there is a lot you can try a little taste at a time. Let her play with the cherios, let her use the spoon, then sooner or later there will be tantrums about potty training, or not taking naps anymore, because that usually how it goes.
