They grow up so fast!
"3 years buddy! 3 beautiful years! You make every minute worth while! We cherish all your firsts and all that is to come ❤ Happy 3rd birthday my love #timesflying #whatayear," the 27-year-old actress and singer wrote. In the montage are a bevy of sweet snapshots of Luca doing a variety of things, like playing with his toys and giving mommy a kiss. He also makes a bunch of funny faces and is shown in front of the Christmas tree one holiday.
Luca's dad and Duff's ex-hubby Mike Comrie is even featured in the clip. There are a few images from a snowy family vacation the trio once took together. Comrie is also shown lying down with his little man during a moment of rest and relaxation. Too darn cute.
Duff and Comrie welcomed Luca back in March 2012. "Welcome to the World Luca Cruz Comrie! Tuesday evening, we became proud parents of a healthy 7 pound 6 ounce beautiful boy," she announced on social media at the time. "We are overjoyed and feel like the luckiest parents in the world...He is surrounded by so much love!! Mom and baby are both doing extremely well."
It's hard to believe how much little Luca's grown up in the past three years!
