Not every story you read to your kids or every album you listen to has to be “educational” or contain a Bible verse or teach some Gospel truth. It’s okay to just read a story because it’s fun. When kids are very young they are still learning language and how to follow a storyline. So really, any story you read will teach them how to do that.
I firmly believe that God created us to enjoy life. What would be the point otherwise? Look up the word “joy” in your concordance sometime and see how often it is mentioned in the Bible in connection with knowing God. Knowing God and being with him is supposed to be a joyful experience. We are supposed to enjoy and appreciate the good things God has given us. Sometimes, that takes the form of a silly story you can laugh at with your child.
