An Idaho man has come up with a way to make bedtime reading easier for parents who have several kids.
He has invented what he calls "Smart PJs."
Juan Murdoch is a realtor and father of six children. Murdoch says the idea of a pajama that entices children to hear a bedtime story or lullaby popped into his head one day, and he got right to work.
The dots on the pajamas are Quick Response, or QR, codes that phones can scan through the free "Smart PJs" app. Each pajama has 50 different codes.
"So then what you do is you just go down and take a picture of one of the dot groups. Make sure you only get one. Hit save," Murdoch explained.
The your smart phone or tablet reads the book, sings the lullaby, or give you interesting facts about different animals - all depending on the code.
