My oldest daughter and my nephew are one week apart. It's hard not to compare. When they were toddlers, I was comparing how he would eat anything (even chowing down on a black bean soup with lots of spices that I made) to the fact that my own daughter wouldn't eat anything but cheese and crackers.
As time has gone on, we've instituted the no thank you bite. Take one bite of everything offered at dinner. I don't think it's resulted in her eating lots of anything new yet, but her tastes have expanded a little beyond cheese and crackers finally.
So with child #2, I hoped for a better eater. And I got one. She didn't eat all her vegetables, but she would try anything and would eat almost everything. Until the other night. I sat her in front of a quesidilla with sour cream and a little bit of refried beans on the side. Without even trying it, she pushed her plate away and said all too distinctly, "I don't like it." Oh, boy.
I'm learning what my sister told me. That even the best eaters go through a picky stage. And this one is just beginning.
