"I have this pit in my stomach constantly, because I’m trying to make life as normal as possible for our other 2 incredible kiddos."
River Smith's family is trying to adjust to life without him.
His mom Amber -- wife of country singer Granger Smith -- shared a heartbreaking post on Sunday, as the family took a trip in honor of the three-year-old, who accidentally drowned just three weeks ago.
In the snap, River's older sister London, 7, and Lincoln, 5, happily pose beside a giant Tyrannosaur fossil.

"Every single thing reminds me of him, and all I can think about is how he would love exploring and seeing all that we are seeing. I see his name everywhere, I see little red-headed toddlers everywhere. I miss his silly personality and his bright light. I see his face in our other kiddos," she wrote.
"I have this pit in my stomach constantly, because I'm trying to make life as normal as possible for our other 2 incredible kiddos, London and Lincoln, while hurting so bad inside," she continued. "I look around at everyone else and wonder if anyone is going through something like we are."

Amber and Granger broke the devastating news earlier this month, after their child drowned at their home in Georgetown, Texas. Last week Granger announced that he would return to touring, but would not be doing any meet-and-greets.
"Don't feel sorry for us because we feel very blessed we had an incredible little boy for three years," he said.
