Nicole Polizzi's baby girl is about to reach a mega-milestone: Tomorrow is Giovanna's very first birthday!

The MTV alum and her hubby Jionni have already begun celebrating their wee one's special day by posting one of the sweetest glamour shots we've ever seen -- aka one of the pics from Giovanna Marie's birthday photo shoot.

All that adorableness got us reminiscing about the past -- and Giovanna's birth, aired during the final season of “Snooki & JWOWW.” All laborious pushing aside, we'd nearly forgotten how absolutely sweet that moment was. When the "Jersey" gal teared up while talking about her babies, we cried right there along with her. When the new mom whispered to Giovanna, “Make sure no boys pick you up in the nursery,” we cackled. We loooove seeing Snooki in mommy mode — she’s a natural!

Join us in taking a trip down memory lane with the clip, below, and leave your birthday wishes for Lorenzo’s little sister in the comments!
