Baby DeBoer has arrived!

Chelsea Houska and Cole DeBoer are the proud parents of a healthy boy, the beaming couple happily shared. While the mama didn't reveal the tot's moniker, it's a safe bet Aubree’s name suggestion for her brother -- Sparkle -- was not the winner!

"Welcome to the world, sweet boy," Chelsea captioned the photograph above, featuring the newborn's hand. AWWW!

The Teen Mom 2 lovebirds announced that they were expecting their first child in July, and both enthusiastically shared updates throughout the pregnancy -- from bump shots to asking whether or not their precious peanut looked more like Chelsea or Cole. The newlyweds soon learned that they would add a “little man” to their brood, and now said sweet son is a brand-new member of the family.

Be sure to offer your congrats to Chelsea, Cole, Aubree and Baby DeBoer in the comments -- and keep watching Teen Mom 2 every Monday at 9/8c! For a sweet rewind, relive Chelsea and Cole telling Aubree about the munchkin in the clip below.
