During a visit to "Today" with her castmates, Polizzi, 32, revealed that she finds filming the show to be "a lot."
"I just feel like it's a lot," said the mother of three. "Especially with Angelo -- I had my third baby -- it's just a lot for me."
Polizzi is mother to Lorenzo, 7, Giovanna, 5, and Angelo, about 9 months.
"I don't have a lot of help [with the kids] when we're filming and it gives me a lot of anxiety," she revealed. "I just have to do what's best for me at the moment."
The reality star also discussed motherhood.
When asked how she'd describe herself as a mother, she joked, "Frickin' awesome!"
Polizzi then addressed her female co-stars' mothering.
Polizzi revealed on the Dec. 6 episode of her podcast "It’s Happening with Snooki & Joey" that she would be leaving the long-running MTV show, which premiered in 2009.
“I love you so much, and don’t hate me for my decision,” she said at the time. “I am retiring from 'Jersey Shore.' I am not coming back to 'Jersey Shore' for season 4 if there is one.
“The main reason is really… I just can’t do it anymore. Literally, leaving my kids to film it is really, really hard on me," Polizzi confessed. "I try and quit every single day. I quit every time we film because I just hate being away from the kids."
