Hi C.,
At this age, Alexandria is more aware of what she does and doesn't like, has her own preferences about tastes and textures. She may want to eat more table food, or on the other hand, not be ready for the textures of certain foods. Just as you have your food preferences, things that you like and do not like, so does she. Continue to introduce and reintroduce foods, but don't force the issue. A lot of times, parents think that their child needs to eat a huge variety of things and it's not true. While you don't want to end up with a child who only eats grilled cheese, macaroni with butter and applesauce, a child doesn't need to eat every fruit and 10 different vegetables and every variety of meat/chicken/fish/protein. As long as you find something from each food group that she likes, her nutrition will be fine. I think that as adults, we would find repetition of the same meals over and over to make us crazy and often it makes parents crazy when the kids want that, but familiar foods that they know they like are comforting to young children.
Good luck!
