Kristen has some suggestions in her book above and Nourishing Traditions for
Baby and Child would have many more (http://amzn.to/10FxbZO) I do not know the age of your son and I am not a nutritionist, however, if it were my child, I would try
bananas, avocados, egg yolks, pieces of pastured liver (cooked), cheese cubes, homemade grain free muffins, pastured butter, some
yummy homemade crackers (have to search for grain free ones... here's one with quinoa that would be good after 12 months... http://www.scratchmommy.com/cheesy-quinoa-crackers/).
For those food lovers, we have some
yummy printed organic
baby bodysuits to complement the toys - pretzel, hot dog, avocado and
banana.
