Suggestions for writer's block

I have an 11 year old daughter who is working on her first novel (she's on page 6).  I gave her an old laptop of mine that she can use to write whenever the mood strikes her.  She said to me the other day that she had writer's block.  I asked her, "Is it just that you don't feel like writing, or you don't know what to write?  If it's the first one, do something else.  If it's the second one, just keep writing.  What is your character doing?  They can't be doing 'nothing' when they wait for you to keep writing, so write about what they do while they wait for you.  Write about them walking around in a circle or something."  Did my advice work?  I don't know; but she went away so I could work on my novel.
