Sarah Snook's First Child with Husband Dave Lawson

The Succession actress, 35, announced on Monday that she had given birth to her first child with,

husband Dave Lawson in an Instagram picture of the two of them watching the HBO series' Sunday finale.

Snook didn't mention her baby in the description of the photo, but she did write a lengthy reflection now that Succession has come to an end.

Snook said, "It's difficult to put into words how much this show has meant to me. It aches my heart that it is over given the places I got to explore and the incredible talent I got to work with.

"But for my heart to be able to shatter at all, it had to be this full of all the memories, 

happy times, struggles, and victories...I'm thankful for it, she continued.

"I just finished watching the last episode of a show that transformed my life. My life has once again shifted as of late.

Thank you for the love and support you've given my baby, Snook continued.
