Peta Murgatroyd revealed that Monday’s Dancing with the Stars premiere was the first time that her son had ever seen her dance.

Indeed, in an Instagram post on Thursday, the professional dancer said that the first episode of season 28 was "extra special" for her because her baby boy got to watch her dance for the first time. The proud 33-year old mom shares her adorable son Shai with husband and DWTS alum Maksim Chmerkovskiy.

“He is at an age now where he can really understand what I am doing, and it made me so happy to have him with me at the #DWTS premiere,” Murgatroyd continued. “He says, ‘Mumma dance work’ and it warms my heart.”

Murgatroyd also added several photos of the night to her Instagram Stories, including ones of her getting ready in her trailer with Shai, dancing with her celebrity partner Lamar Odom and her husband and little boy watching her dance from the audience. She debuted her DWTS career in 2012 on season 13. She then went on to star in 11 seasons. Her most recent was in 2017 for season 25, in which she danced with celebrity partner Nick Lachey.

Her participation in that season also came just months after she welcomed Shai in January with Chmerkovskiy.

“Being a mom to Shai has been the best thing that’s ever happened to me — it’s what makes me happiest,” she previously told PEOPLE. “I would spend every second of the day with him if I could. But I also think it’s good for me to get back to work.”

When Murgatroyd finally did return to the dancing competition series, fans slammed her for missing out on time with her son and allegedly losing weight, according to PEOPLE.

“I read [the comments], but it doesn’t really affect me anymore because I know that I’m a very hands-on mom,” she told PEOPLE Now in Sept. 2018. “I know that I’m always there for him and it was five hours out of my day that I didn’t see him.”

After two years, Murgatroyd made her return to the ballroom on Monday. Regarding her dance with Odom, 39, and why she felt it “couldn’t have gone any better” despite finishing the night at the bottom of the leaderboard, she said: “I am beyond proud of him. Lamar was extremely nervous the whole day, but kept it together and finished the dance with a smile on his face,” she wrote. “The scores last night were harsh and I know they affected Lamar because he has that win or lose mentality.”

When Lamar told her that he felt like he lost, she said it broke her heart. She told him that there was no losing and only growing on Dancing with the Stars.
