A baby boy laid eyes on his father for the very first time with his new glasses, and the adorable moment is warming hearts across the country.

Captain Brandon Caldwell, with the United States Air Force, recently returned from a two-month deployment in Antarctica, coming home to his wife Amanda and their -month-old son Reagan, who started wearing glasses shortly after his dad left.

In the video, Brandon holds his son while singing, “Pat-a-cake, pat-a-cake, baker’s man,” while Reagan dances excitedly in his dad’s arms and looks up at him.

At one point in the song, the happy little boy pauses and rests his head against Brandon’s chest, while the proud dad pulls him close and becomes visibly emotional.

"This was the hardest deployment yet by far and you can see how hard it was for Brandon to be away from Reagan by the emotion he showed when he finally had him in his arms again," Amanda Caldwell told WABC. "Reagan did not skip a beat and is loving having daddy back home."

"This was the first time he got to see his daddy through glasses," Amanda wrote on Facebook. "It’s obvious in this video he loves his daddy."
