A proud mom posted a beautiful video that her daughter made, marking the day her little brother was starting school this year.

Tania Van Bree, wrote on Facebook that Elli created this video to help spread as much information about autism as possible to the classmates at Elm Grove Elementary School who will be surrounding Willem for the next four years.

"Sometimes new kids, or loud places, scare him because his ears and eyes are extra sensitive," she explains.

Elli, in fifth grade, who will be attending the same school until next year, provides 4 tips for how to be prepared for meeting Willem.

"Overall, he's a kid like you and me," she concludes. "And, I hope you love him as much as I do."

The video was even going to be aired during the school announcements.

(You might want to have a tissue nearby as you watch her talk so lovingly about her brother!)
