Picky Eater

It seems as if overnight my son has become a picky eater. In the past I bragged about him eating everything I offered him. I considered it a compliment to my "good cookin". All of a sudden he does not like fruit, hash browns, or grilled cheese sandwich. Is it the soft textures that he no longer likes? He tastes it, pushes it out of his mouth whith his tongue, then drops it on the floor. This toddler stage is presenting ... new challenges.
