So, from what I understand, Graco seats expire in December six years after manufacture no matter what month they were made. This is what I don't get: Mom A buys a seat made in January of 2010. Her seat then expires in December of 2016. Mom B buys a seat with a manufacture date of December of 2010. Her seat would then also expire in December of 2016. So, why does Mom A get almost one more full year of use than Mom B?
