Small kids, starting school may have difficulty knowing which bus to get on.  Here, busses have identifying markers,  it may be a number, letters,  it may be an image.   In this instance a horse.  

This is intended just for the child to learn and help them identify their bus.  I don't believe it should have the Childs name.  Perhaps you might include other information like home room # or teachers name.  

This is really just an example you will want to change to suit your Childs needs. If you could take a picture of the specific identifier for your Childs bus that would probably be best

You will notice in the image that the words at the bottom do not show up very well.  The settings for the letters were set to SCORE.  That has been corrected to Engrave and will show up brighter.  

You can pop your tag in your son/daughters pocket or attach it to their zipper with a ribbon or tie.
