The "Jersey Shore: Family Vacation" star shared an emotional video on Tuesday showing just how far Greyson has come.
She stated, "watching Greyson's journey brings me to tears," adding it "fills me with so much pride and joy."
The MTV star revealed her son's diagnosis with autism in November 2018 and he's come a long way in such a short time.
"I'm the proudest mama out there," JWoww said. She also thanked his teachers and therapists "for their dedication and patience."
The video, posted to her YouTube page, also features Roger.
JWoww's estranged husband is seen taking Greyson to see specialists with the star, as well as spending some quality time with their son.
The clip gives fans insight to the "Jersey Shore" star's effort to give Greyson the best life possible. It follows his development from just three-months-old and the progress he's made today.
JWoww made sure to document everything from learning his ABCs to being able to identify animals.
She got emotional when discussing the little things that parents tend to take for granted.
"To not acknowledging your name or sitting still for literally 30 seconds to doing I can’t even explain it," JWoww stated.
The MTV star's family life has been a rollercoaster of emotions.
As The Blast reported, she recently settled her divorce with Roger after a nasty battle.
During their split, there were allegations of both physical and verbal abuse, and both stars admitted that it was tough being so hostile with children between them.
Both have since moved on and are dating other people.
JWoww's boyfriend even has stepped in to play stepdaddy!
