The coolest thing about having a baby

What's the coolest thing about having a baby? It really depends on whom you ask, but the best feeling in the world, for me, is whenever my little one grabs hold of one of my fingers with her tiny little hands. You would be suprised with her strength and intensity of the grab. She's been able to grab hold ever since she was a just a few days old, but each time, I can't help but thinking it's one of the greatest feelings in the world.
