What a great product! Think about a mom blog with an educational spin. Your product personalizes children's learning and makes it more meaningful. Parents and teachers will love it. Blogs are never an investment without a reward unless you neglect it. Just make a quick post twice a week, include photos, make it topical and not always about your product. Think about reaching out to teachers in your community, get a few testimonials on how the product works, do a video review from a kid's point of view. Lots of things you can do! Good Luck!
There are a lot of mommy bloggers out there. If I were you I would approach the blogs you like and see if they would do a product review/giveaway. Mommy blogs love doing those, just pick your blogs wisely.
I blog a little bit just to have some content on my site. I don't have the time or energy to dedicate to blogging for it to be a big traffic driver.

Our store is trying to provide increased access to high quality developmental play product for exceptional children, and their families.
