She was only 4 months old when she got her death sentence.
Diagnosed with brain cancer when she was only a baby, Ellie Walton died a few years later at the tender age of 4 on Jan. 15, 2017.
"You should be here," her heartbroken mother, Sarah, wrote in a March 15 Facebook post alongside a photo of a box buckled into a child's car seat.
"We made you a custom urn, you would love it baby girl. Unfortunately temporary urns are just boxes, that wasn't good enough for you, so I decorated it, until your perfect urn comes in."

"Driving you home the other day, I was scared, but buckling you in felt normal," the post continues. "Even though None of this is normal, none of this is right. You should be here. Death is so selfish baby girl. My heart is broken."
"I know your in a better place, and yet no place is better than in my arms," Sarah adds. "I know your happy and pain free, and yet I want you here."
According to the Prayers for Ellie Walton Facebook page, Ellie endured 17 surgeries, 28 rounds of chemotherapy and 42 days of radiation therapy.

But she also had a lot of good times.
"In Ellie's four short years, she experienced so much that this world had to offer," her obituary reads. "Ellie got to swim with the dolphins in Hawaii, See dinosaurs in Montana, swim her heart out in Idaho, go to the happiest place on earth, see and play with huge dogs and tiny ponies, ride on a float, witness a first pitch, see the Seahawks play, and possibly the best experience she ever got to witness was the way she changed everyone's life."
Despite her grief, Sarah says she doesn't regret a thing.
"You see baby girl, I would gladly take this pain over and over again, if it meant that I got to be your momma," her Facebook post reads. "Cause had I never known you, I would have never known pure happiness, I would have never known to live every moment as your last, and I would have never known what true bravery, strength, and courage looked like."
Sarah hopes to help other parents, saying she "will fight for these other kids so that no other mom has to buckle in ashes of their babies."
In fewer than five days, Sarah's post garnered over 2,900 reactions, more than 300 shares and over 150 comments.
"Your post has taught me and I am sure so many others, to not take our children for granted," one Facebook user wrote. "Tonight as I tuck my kids into bed I will say an extra I love you and give them a extra kiss. Your in my thoughts and prayers."
