Parenthood is proving to be a lot of fun for Nicole “Snooki” Polizzi and her fiancé Jionni LaValle.

Their 7-month-old son Lorenzo is “good – he’s starting to crawl now,” the slimmed-down Polizzi told PEOPLE Thursday at the WWE Superstars for Sandy Relief fundraiser in New York City. “And he rocks back and forth which is really cute.”

“You can’t rest because you’re not gonna sleep much but it’s awesome,” added LaValle. “It changes you but it’s not hard, it’s fun.”

The reality star is quick to add what a great dad LaValle has proven to be. “He’s amazing, the best I’ve ever seen,” she said. “He’s very hands on, more than most dads are.”

The happy couple were joined by former Jersey Shore castmates Sammi Giancola and Ronnie Ortiz-Magro at the event. And they, too, have joined the Lorenzo fan club. “He’s so cute!” said Giancola. “We love him.”

“We try to go see him,” added Ortiz-Magro. “I like all his pictures on Instagram – he’s like my favorite person on Instagram!”

The reality star’s favorite part of being a mom? “Just looking at him, knowing he’s mine,” she said. “And that he’s going to think I’m the hot mom one day!”

And Lorenzo may still be just a little guy, but his mom already has siblings on her mind. “I would like four total,” she said of future children. “[Jionni] wants three, but I’m going to make him have four.”

“I want at least one girl,” she adds. “But if I have all boys, it’s fine.”

Her top tips for other new moms? “Don’t go crazy. Make time to go to the salon and get yours nails done. And just breathe.”
