I added salt substitute, real butter, white pepper (NOT BLACK as it can stop up the intestines) and stevia or xylitol or sugar to my little ones' food. Cinnamon, nutmeg, and ginger too! My girls especially loved it when I put cinnamon in their oatmeal or applesauce - the ginger I would put in carrots or sweet potatoes, the nutmeg in rice cereal or vanilla custard. Salt substitute is what I used simply because that is what the rest of the family uses - we rarely use real salt and when we do it is sea salt. I put that and the pepper in their peas and green beans. No harm ever came of it and my children are all good eaters - not picky at all and they all enjoy a wide variety of tastes. Good luck to you!
