The Big Bang Theory actress gave birth to her first child with boyfriend Tom Pelphrey, 40, at the end of March, introducing fans to their little one on social media.
In a string of new snaps on her Instagram story, the 37-year-old could be seen posing beside the Ozark star and their little one, making the most of the sunshine by a pool.
She was every inch the proud mom, kissing the top of Matilda’s head, while another upload saw the couple gather for a family selfie while the tot appeared to yawn.
Kaley completed the posts with cute Easter stickers to commemorate the holiday.
The new mom welcomed the tot on March 30 and introduced her to the world on social media soon after.
Taking to the ‘gram armed with a selection of photos, she penned: ‘Introducing, Matilda Carmine Richie Pelphrey, the new light of our lives! We are overjoyed and grateful for this little miracle.
‘Thank you to the doctors , nurses , family and friends who have helped us immensely over the last few days. We are blessed beyond belief.
‘@tommypelphrey didn’t think I could fall even more in love with you, but I did.’
Kaley and Tom made their romance official last May, following the Flight Attendant lead’s divorce from her ex-husband, Karl Cook.
Heaping praise on her beau shortly after, she thanked him for ‘saving her in all the ways’.
She sent fans into a spin in October when she announced that they were set to become parents for the first time, posting photos of a pregnancy test and a giant slice of cake with pink icing.
‘Baby girl Pelphrey coming 2023,’ she said at the time. ‘Beyond blessed and over the moon… I ???? you @tommypelphrey!!!’
Although Kaley shared much of her pregnancy journey online, she kept the name they had chosen for their daughter firmly under wraps – from everyone.
In fact, she unveiled a blanket that her mother had gifted to her with the message ‘Whats her name [sic] scrawled across it.
The Emmy-nominee joked at the time: ‘When no one knows her name, so your mom goes to these lengths LOL!’
