Oh not at all. This is really the age where it's better that she try a lot of different things. My parents were very understanding and accepting that I wanted to play soccer, and take ballet, and play in the dirt when I was her age. I didn't really keep up any of those hobbies as I got older, but they all helped me in some way, so that's what I want to do for Lily.
Let her try whatever strikes her fancy, and see where it leads.
