Over the past year, we've seen Fredrik Eklund take on a daunting task with grace — and this task is even harder than selling a multi-million dollar property. The real estate agent and his husband, Derek Kaplan, are now the proud parents to a beautiful set of twins, Freddy and Milla, and they're already showing the little ones the world. (This tropical trip doesn't look too shabby for a 5-month-old, right?) 

In addition to two loving daddies and an enviable travel history, the babies also have this going for them: an older brother who is clearly madly in love with both of them. Need proof? We have it below!

Derek's son Kai had long been looking forward to having siblings, so we knew that he would be pretty stoked when the twins arrived. But when Derek posted actual video footage of Kai bonding with his brother and sister, we were fighting back tears on the spot.

The videos below show the most precious moments imaginable, starting with the birth of the twins and moving on to show family vacations, snuggling sessions in bed, and Kai holding his little sister with a heart-melting smile on his face. Keep scrolling, hit play, and make sure you have a whole pile of tissues on standby.
