Growing up is hard. Watching someone else grow up can be even harder.

Meet little Sadie. Sadie is a 5-year-old girl who is really, really upset about the fact that her adorable baby brother is going to grow up some day. But who can blame her? He is just so lovable, and his smiles are seriously the cutest.

Sadie also doesn't want to die when she's 100.

We feel you, sweetie.
