discerning palate

Eddie has always been a good eater but lately, pretty much ever since he turned one, he has become pickier and refuses to eat certain things at certain times. I know this is a typical toddler behavior. The funny thing is that he seems to have a sophisticated, discerning palate because the times when he refuses certain foods is because they just aren't the best. For example, for a week he refused to eat his Cheerios. Then I tasted one and realized why - they were stale. Got a fresh box and he is eating them again. Tomatoes. All summer long he has loved eating cherry tomatoes, especially the Sungold variety from the market. He also eats the Juliets we grow in our backyard. But for a week or so he wasn't eating the Juliets anymore. I tasted one and realized why - they just weren't ripe enough. One night I gave him some diced zucchini and spinach that had been frozen and then thawed in the microwave. He wouldn't touch it. It had freezer-burn. He also doesn't like more than one-day old pasta. And he prefers his peas to be fresh too.
