See How Much JWOWW's Daughter Has Grown In Six Months!

The 'Jersey' munchkin is already celebrating her first half-birthday!

Jenni Farley and Roger Mathews have certainly learned something that most parents grasp very early on in their child's lives: Time really does fly when you're raising a scrumptious kiddo -- especially if she's "angel baby" Meilani.

The "Snooki & JWOWW" peanut is already six months old (!!), her adoring folks kindly reminded us with the sweet snapshot below.

"I cannot believe chunk is already six months today!" the "Jersey" gal captioned the delicious pic of her daughter on her website. "She's getting so big so fast!!!"

Yes, it's been half a year since that "god-awful" delivery -- which caused JWOWW to scream like a "dying hyena," according to her BFF Nicole Polizzi.

But let's forget about that experience for now and go back to modern-day Baby M, who has already celebrated a slew of first holidays and developmental milestones. To commemorate the tiny tot's rapid growth, we're taking a fond look back at how much she's evolved in size and personality, thanks to monthly photos (with her trusty stuffed bunny) from Jenni and Rog:
