User blog:Only A Lemon/Child's Point of View Writing Tips

I recently had an idea for a pasta I'd really like to write, and soon. In order to execute this idea properly, however, I would need to write it in the perspective of a young child, maybe four to five years old. I know this can be very tricky- you can't use a great vocabulary, and you don't want to make it sound as if the pasta was written by a child- so I was wondering if anyone had any tips that could help me effectively write in this perspective, but still write well.
