Time just flies by! Eva Longoria took to Instagram on Saturday, March 9, to share a video of her first child, Santiago, and she was quickly reminded that kids certainly grow up in a heartbeat.

The 43-year-old showed a clip to all her fans of her 8-month-old son standing on his own two feet, using a toy for support, and looking back to smile at his mom as Eva asks, “Who is standing up all by himself?” She captioned the video, “He’s growing too fast … #StandingAlready.” Take a look at the adorable video below!

Fans were quick to respond to the clip, with one person saying, “Omg! Look at him! He’s getting so big!!!” Another added, “He’s too cute!!!! You need to have one more angel so he can have a brother or sister.” One user chimed in with, “Miss those moments. Enjoy, they grow so fast.”

The Desperate Housewives alum has of course been all about her baby boy, who she shares with her husband of two years, José Bastón. “He’s always with me,” the actress told Us Weekly back in December, adding that Santi is even around while she films the live-action version of Dora the Explorer and while she directs episodes of Black-ish. “The great thing about the work I do is that I’m able to do that. I’m really grateful. I get to take Santiago to work every day.”

Eva also gushed about motherhood to the outlet, saying, “It’s amazing. Every cliché has come true, but it’s wonderful. I’m really lucky to have such a good boy.” And while she’s an amazing mother, the Overboard costar had nothing but kind words to say about her partner in crime, who already had three kids from a previous marriage to Natalia Esperón.

“He’s an amazing father to his three older children, so I knew that he’d be amazing with Santi,” Eva said. Even if Santi is growing up fast, we know that Eva will take advantage of every second she spends with him.
