I'm getting Kaydan a drawing board you can erase *can't think of the name* for working on his letter and number formation. Bub has a small travel size one that he loves, but you can't get much on the screen.
Kaydan also has a subscription to
Animal Baby. I love it because it has non-fiction and fiction stories. There just aren't enough good non fiction readers out there for non readers and beginning readers (IMO).. so this works great. HTH
