re: Held my grandson for the first time yesterday.

Congratulations, it is an amazing feeling. I immensely love my kids, but there is something about a Grandkid that is so much more special, a love on an entirely different plain. Maybe when your own kids are babies, you're so tied up with just trying to keep your tiny humans alive and growing right and your family intact and surviving as well that you don't have the time to contemplate certain things. Yes to an extent you do, but with a Grandkid you have that luxury. You're older and wiser to this cruel world.
I felt the difference when I realized the depravity I would inflict and the place I would go to, on anyone that would hurt the precious innocent human I had lying on my chest. The primal protection feelings is so strong. Not taking anything away from my kids but grandkids are something different . Both of my parents agree that it's a unique love for a Grandkiddo or Great Grandkiddo.
