Snooki was sad when baby Lorenzo learned how to stand — she thought he was getting too independent — so we can only imagine how she's feeling with this new milestone.

"Lorenzo is now climbing stairs. #heartattack," she tweeted earlier in the week. Baby 'Enzo is growing up — and climbing up — so fast!

It feels like just yesterday that Snooki's mini guido learned how to prop himself up on his own. At that time in early June, she told Wetpaint, "it makes me scared 'cause he can hurt himself." Hey, at least he's not following in his mama's footsteps and dancing on tables just yet!

What do you think of little Lorenzo's newest big boy step? Let us know in the comments below!
