The boys have only one living great grandparent, Kevin's Grandma. Kevin's mom is Gran and my mom is Oma, so they just call her Grandma and have no concept of the "great" part of it.
Grandma lives in Tennessee but the boys got to be with her over Christmas. Here they are Christmas morning.
And now I must go back to my laundry and toy reorganizing demands that inevitalby consume the first day back from a Christmas trip.
