Picky Eater?

As a first time mom, I don't know all of the "normal" things that babies do, and so I worry when Ryan does them. Are babies usually picky when trying new foods? Ryan rejects almost all new foods the first few times he tries them and it is hard to know if he really doesn't like things, or if it is just a new taste he needs to get used to. We are also trying to move away from pureed food, but unless it is pureed, he doesn't want it....unless it is on Mommy's plate!
