Narrations–6 year old

I am reading about two paragraphs of a chapter book to 6 year old my daughter, then asking her to narrate it.  Her narrations are usually very short, as in “They walked on the path [skip lots of events] and then got to the mountain.  That’s all I know.”  What can I do to teach her to narrate more?  Should I include questions after she is done?  I am doing this, and she knows the answers to them, but I want to make sure I am not destroying the process.  (“What happened on the path?” etc.)  After her turn, I read the rest of the chapter, and her 8 year old brother narrates it.  His narration is full and detailed, and she is sitting there hearing it.  Sometimes I narrate instead of the kids when we are short on time, as a model for them.  Will she just pick it up from the modeling?

Note: We have already read and narrated the Aesop’s Fables book, so two paragraphs from a chapter book are what I am trying to do as a “next step.”
