Write a short children's book

I can provide a children's story of up to 1000 words aimed at kids up to 7 years old. I will provide the story only, to which you can add your own illustrations and images if desired. I have ghostwritten over a dozen children's books as well as one of my own.
I have a pre-school daughter who is endlessly bringing books to read, so I have a good idea of what kids look for.
