Walker Colt Pruett weighed just 1lb, 3ozs when he was born at 26 weeks in April of this year.
During that time Erica and Jared decided to keep a daily blog of their son's progress in hospital.
Using the pictures, Bryan created the timelapse video above of Walker's first 80 days.
"She came every single day that he was in the NICU and took a picture of him. After we left the NICU, she did a photoshoot with us. She gave us the complete rights to all those pictures.”
Erica also spoke about what the family went through at that time: "He was just so, so tiny. You couldn’t touch him. You couldn’t rub him. You just had to pat his skin, because his skin was so fragile."
Describing the first time she held her son, Erica added: “I was scared I was going to drown him in tears. It was amazing.”
She said the amount of support the family has received since Walker's birth has been amazing.
Erica said the outpouring of support had been "humbling and amazing".
A post on Friday said Walker was "doing great" after going back to hospital for a hernia surgery.
He now weighs 6lb, 1.4ozs, which is over five times his birth weight.
Walker’s grandmother, Kerry Walker also spoke to the Martinsville Bulletin and said: “I was worried about all three of them, but they were very strong."
“I don’t think I could have handled things like they did. They just immediately took their roles as parents and were advocates for that child when they were in the NICU with him. They made me very proud.”
