I remember my son at 15 months old,,, some of the little meals I made for him were:
a serving (or half a serving) of cottage cheese with various types of fruit, and after he ate that then I would offer a piece of Sun Maid Raisin bread (no high fructose corn syrup in that one)
I bought Smart Dogs - in the produce section, they are Veggie Dogs. he would eat one every other day or so with again a differnt type of fruit and/or sweet potato
in the organic section Dr Praegers Spinach pancakes, he loved them! for the longest time he ate one everyday, to get him use to them I would serve them with cut up apples or pears, so he had the sweet flavor as well.
Fish sticks, Dr Praegers <not a big fan of breaded things, but it's fish!..so at least he's getting something good out of it> and Dr Praegers stuff seemed to be a bit healthier than the norm...
Also there is a great book out there, Super Baby Food, it's a purple book, I still use it as a reference and he's almost 3. It has everything from picking cooking and storing different foods, to using food/non toxic things for crafts, and tons of good recipes.
I always tried to follow the feed him a rainbow every day rule to make sure he got all his nurients. I introduced Blueberries with cottage cheese and gave him cheerios too,, he had a blast putting things in his cottage cheese then eating it. Oh and i use to buy the large curd cause it was easier to finger eat until he started with a spoon.
Good Luck, I hope i helped.
