Feeding Little Man prunes worked quite a bit better than we had anticipated, and we've decided to cut back and save those for times when he might need some help 'moving things along'.
Next on our list of fruits to try is bananas. We tried them plain, and he was not having it. So we mixed them with Oatmeal, and he appears to tolerate them. Bananas may not turn out to be his favorite fruit, but we're more concerned about teaching him to eat what is served than serving him what he likes. So far, so good.
