Swish, swash, swoosh, swosh, wash the clothes so fine ("draw" a side-lying figure 8 on their back with my fingers repeatedly)
Wring them, wring them (wrap their arms around themselves and squeeze)
And hang them on the line (lift their arms above their heads)
I also do "Round and Round the garden" on their hands and "This little piggy" on their toes. These may all seem simple and silly, and they are, but they are a lovely way to help children gather themselves, regain focus, and also connect with a caring person! They also help a child develop body awareness which is handy for all gross and fine motor skills later on.
