Meghan Trainor is wishing husband Daryl Sabara a happy birthday!

On Monday, the "All About That Bass" singer shared a sweet video of herself and Sabara with their infant son Riley in honor of the actor's 29th trip around the sun. In the clip, Riley sits on his mom's lap while his parents take turns saying, "I love you."

After a few moments, the baby responds with an adorable babble that sounds pretty similar to "I love you," earning cheers from all the adults in the room and excited grins from Trainor and Sabara.

"Happy birthday @darylsabara !" Trainor, 27, captioned the post. "You'll never know how much we love you❤️"

Trainor first met Sabara in 2014 at a Los Angeles house party before her rise to fame later that year. Then in 2016, mutual friend Chloë Grace Moretz played matchmaker and sparks flew between the pair. After a year of dating, Sabara proposed to Trainor in front of her family during a trip to Palm Springs in December 2017. They wed on Dec. 22, 2018.

Trainor welcomed Riley, her first child, on Feb. 8 of this year. The singer and Sabara announced the news on Instagram almost a week later along with photos of the family of three at the hospital.

"This sweet baby boy's due date was today on Valentine's Day 💝 We got to meet him Monday, Feb 8th! We are SO IN LOVE 🥰😭 Thank you @darylsabara for the best Valentine's gift ever! Welcome to the world Riley!" Trainor shared at the time.

The new mom has been open about how the infant had a "rocky start," revealing during an interview with Today in early June that her newborn was breech and had "breathing issues" immediately after her c-section delivery.

"It was one of those horror stories where he didn't cry," Trainor said of her son. "He didn't make noise when he came out. I was like, 'Why isn't he crying?'"

Listen below to our daily podcast PEOPLE Every Day for more on the sweet moment of Meghan Trainor and Daryl Sabara's son Riley saying "I love you."

Doctors then told Trainor that Riley was having breathing issues, which the first-time mom recalled "was terrifying." Riley, now four months old, was immediately rushed to the neonatal intensive care unit and had to have a feeding tube.

"I got to see him for one second before they took him away," Trainor told Today. "That was probably the worst part...But we're so lucky we got to bring him home after five days."

Back in April, Trainor posted a video to TikTok, documenting Riley's early days.

"We had a rocky start.. but Riley is perfect, happy and healthy 💙," Trainor wrote. "So lucky to be your mama sweet boy."
