There is a קיצור שלחן ערוך that is called מקור חיים. It was written in the ‘60’s or ‘70’s by Rabbi Chaim David Halevi, who eventually became Sephardic Chief Rabbi of Tel Aviv.
His book is used in many schools in Israel, as he brings both Ashkenazi and Sephardic customs. His writing style is clear and understandable.
The מקור חיים, as he was known, made a very strong point regarding the Seder. The children are the most important people at the Seder. They must be kept involved and everything should focus on them.
We must fulfill the והגדת לבנך, tell your children, through them. They are the future. And we must never minimize the impression that a well run Seder can make on them.
We are to try to keep them awake and encourage them to ask questions.
We began as a nation in Egypt, and we must continue with our future generations by telling them the story of Egypt.
