The proud mama posted another hilarious tweet today, joking about how nice her little one's crib is.
"If Otis was on Cribs, his crib would win," she wrote.
"I wish I could fit in it. Thanks, @SerenaandLily for the lovely gifts. Do you make adult swaddles?"
And less than 24 hours after Wilde revealed that she had given birth to her first child with fiancé Jason Sudeikis, she was cracking jokes about her baby.
"Having an infant son alerts me to the fact that every man, at one point, has peed on his own face. #awesome," she tweeted.
The brunette beauty and her fiancé, became parents on Sunday, April 20.
She tweeted the big baby announcement and shared his adorable name with the world, writing, "Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I'm the building)."
She added a black and white photo of little Otis wrapped up in a blanket and cuddling his mama. So sweet!
Wilde is seen smiling with her eyes closed and resting her head on her son in the adorable mommy-son photo.
