Leslie and Jamie's newborn daughter didn't like sleeping flat when she was born. The only way for everybody to get any sleep was to put her in the car seat or swing. Leslie kept asking the rhetorical question, why hasn't anybody made a foam mattress shaped like a car seat? It then came to her and the process started slowly and gained significant speed as 2008 got underway. Once they found the right foam manufacturer, the design was finalized! And Nap Nanny was then born!
