Snooki’s baby Lorenzo has been hitting a lot of milestones lately — can you believe he’s already climbing up stairs? And now, he’s had a first that any mother would be proud of: baby’s first fistfight. Lorenzo’s not even a year old yet, but he’s already a tough guy!

Over the weekend, Snooki uploaded a video of Lorenzo beating her up. She pretended that it hurt, but we could tell she was loving it. Total cuteness overload. We can’t believe how big Lorenzo’s gotten!

Has Snooki been teaching Lorenzo how to lift? Her former Jersey Shore castmates would be so proud.

And a quick note to Snooki: more Lorenzo videos, please! We love watching her little heavyweight-in-training grow up, especially since we were there from the beginning. If she doesn’t start posting, we’re going to just have to make GIFs with all the pics she posts. Well, that or just wait until Snooki & JWOWW Season 3, in which he will clearly steal the show!

What do you think of Snooki’s latest (and most adorable) Instagram vid? Sound off in the comments!
