Why am I just learning about these now?  An Idaho father created 'Smart Pajamas' that will read stories to your little ones.  The stories include classics like Humpty Dumpty, Cinderella and more.  The PJ's have polka dot symbols on them that work as codes. You use an app on your smart phone to scan a code and each code brings up a different story.  The Smart PJ's are $29.99 online and made for both boys and girls.
