如何创作一首简单的幼儿儿歌？

I decided to create my own simple rhymes for the children. Here they are:

I and Mom both have hands. Both have handprints on our palms, And ten fingers in each palm too. I want to tie my shoes alone, And I'll help Mom clean up after.

Rhyme No. 2: Friends

Three best friends, a monkey, a cat, and a dog. One two three, we flip like a coin. Four five six, ice skates roll. Seven eight nine, play with a ball. You find him, wave your hand, He finds you, we're all good friends together!
