The Gossip Girl star revealed her pregnancy this week through a candid photo of her adorable bump taken by her brother, Eric Lively.
The actress has now shared more snaps, this time from her baby shower.
She wrote: "With a new baby on the way there is so much to do! But before experiencing the joy of 3am screams, seemingly impossible amounts of poop and having a favourite shirt covered in reflux...’
‘There are presents to open, onesies to dye, there is cake to serve, advice to be shared and all around celebration to be had. And that we did..."
The actress previously shared her excitement about becoming a parent with husband Ryan Reynolds, who she married in 2012.
She told a US magazine: “He's going to be a great father and patriarch - he's so meant to be all those things.”
Ryan previously said in an interview: “We’d love to have a big family. We both come from big families - my parents did four. Blake's did five.
“A lot of people say it's crazy, but we'll only know when we're there, you know? We'll walk through that fire pretty happily, I think.”
That’s one very lucky baba!
