Ask questions about what you just read. Let your child narrate back to you.  You will be able to tell how much he understood. Encourage the children to answer in complete sentences.

The Word Does not Return Void!

Keep in mind that devotions don't have to be a super spiritual to be spiritual moments. The word does not return void! You are planting seeds and it may take time to see results.

Keep Little Hands Busy

Various Bible coloring books are available. Or you can encourage your child to draw what you are reading about on plain paper with crayons or colored pencils. I made felt boards by sewing two different colors of felt together with a piece of cardboard between the layers to add stiffness.  The children used these to make pictures on the felt during times when I wanted to keep them quiet.  Purchase precut felt squares and cut them down to fit into the large zipping baggies.  Cut the excess felt from each square into various shapes.    Cut the cardboard about 1/2" smaller than the felt squares.  Sew a straight stitch about 1/4" from the edge.  If you don't sew, you can use a hot glue gun, following safety precautions.  Store them in a large baggie.

Here are outlines of the book of Mark, Matthew, Luke and John.
