The logo will be used primarily on the client's website, LearningSocialRules.com. The website will represent a children's book author, who writes books that are designed to be read by adults to autistic children and teach them how to behave. The website is envisioned to eventually become a community for parents with autistic children.

The target audience for the website (and the logo) are parents with autistic children.
The goal is to create a logo. Trying to convey both the "happy" and "social" concepts.
Also need to keep in mind that although the website is about autistic children, and a book for autistic children, it's target is adults.
