Ace Eicher, Girl, Explains Why Brother With Down Syndrome Is Just Like Any Other Kid (VIDEO)

WATCH: Sister's Touching Tribute For Brother With Down Syndrome

"Whatever, I'm just happy he's my brother."

Big sister Ace is out to deliver an important message: Her brother Archie has Down Syndrome, but he is just like other kids.

He still jumps on the bed, eats ice-cream, plays in the pool, and in classic little-brother fashion, gets on Ace's nerves from time to time.

So, why do people think he's different?

"My mommy tried to explain it to me, but I don't still understand," Ace says.

Archie was born in Bulgaria, and then adopted by Ace's family. Big sister made the video for him in honor of World Down Syndrome Day, which took place on March 21. Since then, she's racked up quite a following -- currently, the video has almost 90,000 views on YouTube.

Watch now to see a little girl's touching tribute to her adorable little brother, who she calls her best friend -- and prepare to be completely charmed.
