I was not aware of this fact until I wrote a book for children myself but curating and creating content for children is an arduous task. You have to incorporate the highest levels of user engagement in order to make sure the book stacks. Your book also needs to be simple and engaging enough to keep the user intrigued with your content. If you want to get an illustration designed then you should spend most of your time before you commence with writing to look for the best children book illustration services and work alongside professional illustrators to formalize and give your book a visual appeal.
