Use three things a child has said in a poem, with repetition. Like:
That is inside, this is outside.
You need to come upstairs with me.
I want another puzzle.
Try beginning with different techniques: google-searches, personal notes, reflections. Try the actual things in different ways. Sit and imagine different people saying these to you. Imagine the President saying these things in speeches. Think of someone you have had a conflict with saying this to you. Your friend says this to you.
