Kailyn Lowry and her husband, Javi Marroquin, have one thing on their collective brain: babies! These two have only been married for a few months (and their official wedding won't go down until this fall), but they're already chomping at the bit to get pregnant.

"Can't wait until our family grows!" Javi posted to Instagram on February 21, along with an adorable family photo of himself, Kailyn, and Kailyn's son, Isaac.

Wow, this Air Man is one eager beaver! Of course, Javi and Kailyn probably won't get knocked up until he returns from Air Force Tech Training and they get married (again) — unless Kailyn wants to rock a baby bump at her wedding...

Either way, these two seem more than ready to have a child! Not only are they already hitched, they're extremely mature, responsible, and (most importantly) over the age of 16. Plus, Isaac would make the best big brother ever! Sigh, finally he'll have a Woody to his Buzz Lightyear.

Do you think Kailyn and Javi are ready for a baby? Hit the comments and pour your hearts out!
