Seder
A Haggadah is a book that contains the religious ceremony for the first night of Passover (outside of Israel the ceremony is held on the first 2 nights of Passover).
Twice! The first two nights are Seders, and you read it once at each one.
It's not a prayer. In the Haggadah, which is used for the seder, there is the story of the Exodus which we read.
You can't "make" your kid understand anything, but you can have a child's Haggadah to read to your child.
It is not known for certain who authored the Haggadah.
The Haggadah contains the service for the seder.
The text of the Haggadah can be found and read at various places and in various ways online. There are websites with parts of Passover Haggadahs available for download, and the entire Haggadah can be found at Chabad Organization's website.
Moses is never directly mentioned in the Haggadah.
