"do whack a do whack a do, whack whack whack"
My father in law started singing this nonsense song to my daughter the other day.
And it was cute when she would run through the halls shrieking "whack a do!!" - the first hundred times.
Now, it's become a phrase she says with every breath - describing everything: "I'm a whack a do!".
It's the joy of two year olds that they find delight in the smallest things. They can also drive you nuts if you let them.
