Ashley's Prayer layout

Well here is today's layout:

I'm happy with it. I used one of those scrapbook recorders and captured Ashley saying her prayer. She says it in her sweet high pitched voice.

Ok so now for a question: When writing Ashley's word I'ma. How should I write it? It's pronouced I'm uh. So should I write 1. I'ma 2. Im'a 3. Ima 4. I'm uh?

Thanks for looking!
