The couple welcomed their first baby together in March.

Last week, Cuoco shared a sweet photo of Matilda and her dog Opal cuddling. In one photo, Matilda touched noses with Opal as she cuddled up on the couch. Cuoco added a "besties" sticker to the image.

In another close-up picture, Matilda and Opal stared into each other's eyes. "She always gets so excited when Opal comes to give her kissies!" wrote the proud mom.

Since giving birth in March, Cuoco has shared several photos of Matilda on her Instagram. In May, The Big Bang Theory star shared a hilarious video on her Instagram Story where Cuoco wore a black T-shirt and baggy pants while holding her daughter. As music from the Jonas Brothers music played, Cuoco noticed that Matilda's meltdown subsided.

"Not kidding. Was screaming," Cuoco captioned the story. "Turned on @jonasbrothers. Stopped crying lol we have a fan here folks."

In April, Cuoco exclusively told PEOPLE about her life as a first-time mom and how "natural" Pelphrey is as a dad.

"I cannot believe how natural he is, how much he loves it," she said. "I mean, when we were in the hospital, he did everything — every diaper, he's the swaddle king. All the nurses said, 'Oh my God, you're the best guy swaddler we've ever seen."
