All three of those foods are very good. I give Koda a topper every meal. I alternate between plain yogurt, scrambled or boiled eggs ( she is two so gets two eggs when she gets them), peanut butter, especially prepared chicken which is then shredded, cottage cheese crumbled, etc.
Wet/canned food can cause diarrhea.
I also give my girl some raw with all her meals
