What This Little Girl’s Crying About Is LITERALLY The Most Adorable Thing You Will See In Your Entire Life

When 5-year-old Sadie found out that her new baby brother wouldn’t stay so small forever, and one day would grow up, she had the most adorable life crises ever. I just love how her little brother keeps smiling at her the whole time. Not understanding what all the fuss is about… Awww.

You have to see this, it’s quite possibly the sweetest thing ever.
