And here is a fun hand washing poem

10 Little Fishies
A Hand Washing Poem/Song for Little Children by Susan Perrow 

I have 10 little fishies, 
That love the washing rule. 
They have so many swims each day, 
In water clean and cool. 

Each little fishy finger, 
Gets a soapy bubbly rub.
 From its head down to its tail, 
Then I rinse them in the tub. 

My fishies need to have 
Many swims and rubs each day - 
Before I eat my food, 
And after every play.

 Each little fishy finger, 
When I have used the loo, 
Enjoys two soapy rubs, 
Such important work to do! 

Each time the fun is over, 
I shake the water free, 
Then dry the fishy fingers, 
That all belong to me!
