Many things to choose from. Soups, eggs, applesauce, quiche, pudding, yogurt, mashed potatoes, smoothies, ground meats, fish, sweet potatoes, pancakes and bananas.
I am sure you can add to the list. Just think that you are cutting things up for an eighteen month old child. Chew by grinding small circles on back teeth slowly. No up/down biting. Get food on both sides at same time. Takes work !
