Reality star Jenni became a first-time when she gave birth to Meilani in July, while Snooki's son Lorenzo has just turned two.
Posting a sweet snap to Instagram, Jwoww simply said: "Counting toes."
It's no surprise that Jwoww and Snooki's kids would be firm friends from an early age given how close their mums are.
We watched Jwoww and Snooki getting wild and partying up a storm on Jersey Shore before they both settled down in their lives.
Their new reality show, Snooki & Jwoww, shows a very different pair: both in long-term relatonships and both now mums.
Jwoww is engaged to trainer Roger Mathews, while Snooki is engaged to Jionni LaValle. Snooki's currently pregnant with her and Jionni's second child.
