Yes, how old are your children? Is this their first attempt at narration? It is harder than it seems. I started my children off narrating from Aesop’s Fables. They are very short and mostly with one scene in the story. They were very successful at these, and success for them meant they liked it. We worked up from there with story type reading (as opposed to informational readings -which are the hardest to narrate).
And, no, my children didn’t just love narration, but it was something we did and they got used to it and do it without complaining now.
