Nicole Polizzi and her fiance Jionni LaValle just welcomed their baby girl with open arms, but we're betting the "Snooki & JWOWW" star and her longtime love are not the only ones excited about the new addition.

The couple's adorable son Lorenzo is no doubt delighted by the debut of his little sister, named Giovanna Marie. And while a new arrival to the family fold will mean some changes and adjustments for the two-year-old -- plus there's that sibling rivalry thing -- we're more than sure Lil' Enzo will rise to the occasion.

Here are all the reasons we think he'll make the best big brother ever:

He'll teach her the alphabet

And share some healthy snacks while they're at it.

He'll be her soccer coach

We've already got a mini David Beckham in the making -- and the new addition could turn out to be the next Mia Hamm.

He'll inform her that cuddling is key

After all, it's the way to their doting mama's heart.

He'll play dress-up

Borrowing Mom's sneakers is always enjoyable -- and who doesn't want to walk a mile in Snooki's shoes?

He'll show her that stickers = endless fun

And they also serve as excellent decorations for Mommy's legs!

He'll play peekaboo

Because, let's face it, it's always a big hit with the petite ones.

He'll make sure she's got killer dance moves

When the music plays, Lorenzo knows it's impossible to stand still and not move to the beat.

Most importantly, he'll tell her that flowers are the perfect way to make Mommy happy

And presenting them with a big smile is a plus!
