Three-year-olds in Pre-Kindergarten

I was teaching three-year-olds in pre-kindergarten. Every day at meals or snack time this little boy would refuse to wash his hands. This went on for about three weeks, to show his independence I assume.

Finally one day I told him that he wouldn't receive his snack until he washed his hands. I explained that even Jesus washed before meal times because we have germs that can make us sick.
