InstagramThere was a big reason to fist pump at JWoww's house.
On Monday night, the Jersey Shore: Family Vacation star revealed she and her kids were celebrating a special milestone for her 3-year-old son, Greyson Valor Mathews.
Back in November 2018, the reality star mom of two shared publicly that her son had been diagnosed with autism. Now, just over a year later, Greyson and his family have another reason to cheer.
"Epic day for @greysonmathews," his mom wrote on Instagram. "We celebrate all of his milestones but especially this one... he went all by himself and was so excited to show me. Deff saving this video for his future girlfriend #HappyFirstPoopyOnThePotty #Browniecake."
In the footage, fans can hear JWoww and her 5-year-old daughter Meilani singing "Happy first poopy on the potty day" to the youngster while his famous mom carried a brownie cake with lit candles in it.
Greyson happily blew out the candles, followed by a sweet hug from his older sister.
The heartwarming clip spurred plenty of supportive comments and questions from fellow parents online.
"Awww and sister says 'need help? There you go.' My heart melts ! Way to go Greyson!!" one viewer wrote.
Now, with the new year just hours away, the proud mom is looking forward to the new decade with new goals, the first of which is related to her son.
"At the top of my list is continuing to give back to @kulturecity, who have done so much for me and my @greysonmathews," she wrote on Instagram, referencing the organization that works to foster accessibility and promote acceptance and inclusion for people living with disabilities.
Congratulations, Greyson!
