Jesse Tyler Ferguson and Justin Mikita are celebrating their son on a very special day!

On Thursday, the two actors each posted on Instagram in celebration of son Beckett Mercer's second birthday.

"You arrived into this world 2 years ago today and my life changed forever," the Modern Family alum, 46, captioned an overhead image of the toddler looking at a Take Me Out Playbill in his hands. (Ferguson plays Mason Marzac in the Broadway production, which opened in April after being delayed through the pandemic.)

He added, "My greatest joy is being your papa. I love you. Happy Birthday!"

On his own page, Mikita, 36, wrote, "Happy 2nd bday to this sweet, incredible, smart, loving, joyful and endlessly amusing creature. Love you Beckett!" The photo he shared showed Beckett in a restaurant high-chair, holding a plate to his face.

In May, Ferguson told PEOPLE that Beckett already "loves to perform as well."

"Maybe he caught the bug early," Ferguson mused while at the Tony Awards nominees press event. "We're starting him with Sesame Street. We've shown him some videos of me performing. He's excited to see me on stage. It's exciting for him."

The month prior, Ferguson shared a picture of Beckett in his stroller pointing up to a life-size photo of his dad outside the Helen Hayes Theater.

"Beckett isn't sure why papa is all over this block in nyc," Ferguson captioned the adorable snapshot.

"There is a lot of really horrible stuff going on in the world right now, so Justin and I wanted to share a little bit of good news with you," Ferguson said. "We are expanding our family."

They then hinted at his second child's due date, stating that Beckett will become a big brother "this fall."
