This is one of the sweetest things that I've ever seen!

We hear so much about sibling rivalry, and the jealousy of older kids when babies come into their family. But this little girl just wants her baby brother to remain a baby forever. 

Sadie, 5, simply cannot handle the fact that her baby brother will some day cease to be a baby. And baby brother just smiles up at her because he loves her so very much.

It just about breaks your heart when she says, "And I don't wanna die when I'm a hundred!!!"

It's okay, Sadie, I'm sure you still have many, many years ahead of you (at least 95 years until you're a hundred.)
