Any sort of fruit or roasted/steamed vegetables cut into sticks or chunks, peas, steamed corn, rice cakes with all sorts of spreads (avocado, hummus, nut butter), strips of chicken, fish, other meats. Do you eat oats? I know some people who have to be gluten free can't, but oats or another porridge like thing or yorgurt in a bowl, which she can dip her fingers in and feed herself. Soups, especially blended ones, are great for this too. Any sort of gluten free cereal (we do shredded wheat, but whatever you would use yourself at home) softened in milk with a bit of fruit puree to sweeten it. Do you use gluten free bread? Toast with any sort of spread. Fried or scrambled egg, my daughter is a big fan of quiche, which you can easily bake as crustless in a muffin tray (basically beaten egg with anything you want in it poured into a greased or silicon muffin tray and baked, we often do herbs and cheese or salmon). Sticks of cheese or some people do grated cheese. Basically, you can try almost anything you would eat yourselves, apart from honey and whole nuts at that age.
