Why is this night different from all other nights? Because, Teen Mom fans, on February 23 we celebrate the miracle of life and the anniversary of Sophia Abraham's birth! Four years ago today, Farrah Abraham pushed out her little bundle of joy on national television and the world hasn't been the same since.

Can you believe Farrah's mini-me is already 4? It seems like only yesterday she was walking around with a bright pink binkie in her mouth … oh, wait, it was! But thanks to a recent visit from the elusive Passy Fairy, little Sophia has given up her cherished pacifier in return for some big girl perfume.

No word yet on what Farrah's giving Sophia for this milestone, but we wouldn't be surprised if she got her first pair of high heels. It's not easy following in the designer footsteps of Suri Cruise, but someone's gotta do it!

"Hiding presents in the house for Sophia's #BirthdayPresents Shhhhh! It's hard keeping a secret," Farrah wrote on Twitter on Feb. 21, adding that she's "in shock" that her little girl is already so grown up.

Aww, we're getting all verklempt! Talk amongst yourselves.
