CUTE VIDEO: Girl sobs because her baby brother will grow up

Have you ever seen a baby smile and thought, "I wish you could stay this cute forever"?

Sadie is only five, but she knows exactly how you feel. Maybe too well. When the big sister got worked up because she realized her brother would one day outgrow his "cute little smiles," her parents decided to capture the moment.

If only she knew how cute she is, too. Keep being such a loving big sister, Sadie. Even if you both live to be a hundreeeeed.
