Their love is as deep as the ocean!

Alexa PenaVega and Carlos PenaVega, who tied the knot in January 2014, welcomed their first child, son Ocean, on Dec. 9.

The duo wasted no time introducing their baby boy to their Instagram followers.

"8.6 lb blessing. #OceanPenaVega #WelcomeHomeLilO," the new mom captioned a photo of herself staring adoringly at little Ocean as he rested on her chest.

Carlos also chronicled his son's arrival on the photo-sharing platform.

"The moment life changed forever. #welcomehomeLilO #12/7/16 #8pound6ounceblessing #GodisGreat," he wrote in the caption of a dark photo of himself and his wife bonding with their newborn.

Earlier in the day, the proud papa took to Instagram to share a behind-the-scenes look at the hospital room where Alexa gave birth.

"A glimpse into the past 48 hours #oceanpenavega," he captioned a photo of himself planting a kiss on his wife's forehead as they held hands.

The Big Time Rush alum also tweeted about his first day as a parent -- and his anxiety about having his little one at home!

"Got peed on tonight AND dealing with night 1 at home baby paranoia.. Cant help but check on him after every little sound he makes. #dadlife," the Big Time Rush alum tweeted.

The social-media-savvy duo haven't shied away from sharing details about the new addition to their family in the months leading up to his birth.

They announced that they were expecting on Instagram in June and revealed in August on the photo-sharing platform that they intended to name their son Ocean King.

"Ocean King PenaVega 💙💙💙 We can't wait to meet this little Blessing. #BabyPenaVega #MyLilMan (For those asking about our name choice... :) -God called the dry ground 'land' and the water the 'seas'. And God saw that it was good.- That is why we went with Ocean. And he is a son of the one true 'King'. For us it has a beautiful biblical meaning," Alexa captioned a sonogram while explaining the meaning of her son's name.
