EMMETT, Idaho --An Idaho mother urged parents to "hold your babies tight" in a heartbreaking Facebook post as she mourns the loss of her 4-year-old son.
Ashley Grimm, 31, of Emmett, Idaho, wrote the message following a recent car accident that took the life of her little boy, Titus.
The mother of six posted the message to Facebook on July 15. Since then, it has been shared more than 400,000 times.
"It was my way of journaling the lessons that I had been learning and pouring my heart out in a raw, transparent way," Grimm told ABC News. "I never dreamed that it would touch so many lives. I'm just a person and I lay in bed and cry. I'm not this superhero mom. People that have lost children, I want them to know that it's not out of the question, that they can [get through it]. It's one day at a time.
"My kids, they're already lost their brother," she added. "I said [to myself], 'You have to get up and be strong, or they're going to lose their mother too.' That's what keeps me going."
Grimm and her husband Nick were taking their seven children to Garden Valley, Idaho, for a family reunion on June 2. Grimm drove the couple's truck with five kids in the back, while Nick took the couple's motor home with the two other kids.
Grimm said a large rock rolled in her path while she was driving 45 mph.
"It's a place that's notorious for falling rocks," she said. "It's a dangerous highway, but I saw the rock and I thought I could clear it. I was thinking, 'I'm going to straddle the rock,' but the rock hit my axle and it spun us straight to the side of the cliff."
Grimm said the impact left her trapped in the car. Titus' body was ejected from the vehicle and he was trapped under the van. Grimm would later learn from her son Jude, 8, that Titus had unbuckled his seat belt to switch seats with his brother, she said.
"Everyone was crying and screaming," she added. "I don't know how, but [Titus] was out of the vehicle and I can't even remember what part [of the van] was on him. I just tried to lift it and poor Jude was trying to help me. At this point, people were stopping and calling 911. I just rubbed his tummy. At that time, I was just in denial. I knew in my mind he wasn't breathing, but I wouldn't believe it. I was convinced he would be resuscitated. I didn't know that he had died at the scene."
Police and paramedics who arrived at the scene informed Grimm that Titus had not survived the crash. The other children were not injured and Grimm suffered from wounds caused by shattered glass. That day, Grimm said the only injury she felt was a "broken heart."
