Put on your party hats and stuff your face full of cupcakes, because today, May 18, is Baby Carly's third birthday!

This adorable toddler came into the world thanks to Catelynn Lowell and Tyler Baltierra's teenage sexy time, but they bravely gave her up for adoption to a wonderful couple named Brandon and Teresa Davis.

Cate and Ty are still in touch with Carly and see her on a semi-regular basis (they have an "open adoption"), and we're sure they're going to celebrate her birthday in style with a giant cake!

Show your support for Tyler and Catelynn by sending happy birthday wishes to Baby Cary @CatelynnLowell and @TylerBaltierra –– and make sure to snack of some sugary treats in celebration of this little gal's b-day!
