C.,
I think this is not a problem at all but fantastic!! We used to call our daughter a little begger because she would always beg for what daddy was eating off of his plate. This is wonderful especially at her age. You will very soon be feeding her exactly that, what's on your plates!! anyways. So I think it a great thing, she is curious, she gets to try different flavors, and I truly believe it will make her a better eater in the long run. My daughter is an awesome eater, she eats salmon, sirloin, broccoli, squash, you name it, and she loves it. She is very healthy. Take this as a great thing and enjoy her experimenting!
Good luck to you, I think you have NO PROBLEMS here!!
Take care,
