Should I Write Children’s Books?
The number one reason (and possibly the only reason with the state of the current business model) is that you love them. The pictures, the poetry, the capacity to appeal to both the child and the child inside all of us. If that is your focus, you will do well. Even in traditional publishing, advances are normally very small for picture books. Trad publishers face the same expense issues you do, mostly high printing costs, and paying both an author and an illustrator. So, throw profit considerations out the window (it can happen, but it's tough), and do it for the love of the books and the children who read them.
