More good advice and questions. I am sending it around to a handful of friends, reading it to my kids, some of their friends. It's doing pretty well. It's no Dr. Seuss, but it has some cute little rhymes and ideas. If I were accused of ripping anything off, I'd say stylistically it mildly resembles Weird Al's "When I Grow Up".
I'm more after this as a fun hobby and creative outlet, that ideally, I would like to break even on, or lose no more than a grand. If either of those happened, I'd consider it enough of a learning experience to be a success.
In terms of "sales and marketing", that's literally my day job, and while I'm pretty darn humble about what I do day to day, I'm kinda starting to realize that I'm fairly good at it. Nothing earth-shattering, but in my mind I want to sell one for every one that I give away. Do readings at local libraries, hit up independent bookstores. Give readings kid Q&A's at pre-schools (there's one that my kids have gone to that has a hundred or more kids over the course of the day). It would really be a grassroots sort of thing. If I sell 25, giveaway 25, hurray for me. I'll be a published author, my kids will have a book they can hold in their hands which lists their dad as the author, and I can add it to the list of fun things I've done.
Looooonger term, I also write stuff purely as a brain dump, but it's more catered to a non-kid crowd. The thought is that if I can learn the process at a relatively low cost, on a children's book that I feel good about, if/when the time comes that I really want to chase writing as a side job, I'm now "published author ____" instead of "first time writer ____". Again, the marketing side of things. Having a bigger name than nothing, when trying to publish a short story/novel would be helpful.
So don't let the short amount of time it took to write, make it appear that little thought went into it. There is a continuous refinement process, and I think the illustrations are going to be critical in making it more entertaining, but for a short, simple, mildly funny children's book, I think it's worth doing.
