The new mom looks sleepy and happy in her latest selfie.
The 37-year-old actress holds her daughter close to her chest with the help of a baby wrap, as she relaxes on the couch. She's rocking a signature mom bun on top of her head, and appears to be glowing with no makeup at all.
Cuoco has been making an impressive reemergence into the red carpet world just weeks into her postpartum experience. She joined Pelphrey for their first post-baby date night at the Hollywood premiere of his new series, Love & Death, in April. Then, earlier this month, she stepped out again on Matilda's five-week birthday for the the John Ritter Foundation’s 20th annual Fundraiser: An Evening From the Heart in Los Angeles.
"Everyone's happy, everyone's good," Cuoco told ET of her baby. "She's thriving, she's the best!"
While Cuoco said that she and Pelphrey have enjoyed getting a chance to go out and spend some time together, she also admitted that she's "so obsessed" with her baby girl, and spends all the time with her just in awe.
"She's amazing. She's five weeks old and she was laughing today, full on laughing and I was like, 'This kid is hysterical!'" Cuoco shared, adding, "I've become that mom who posts every freaking thing. She does something, and I'm like, 'I have to post that!'"
The Flight Attendant star also recently opened up to ET at the star-studded Rock4EB! fundraiser at a private residence in Malibu, California, which benefits the Epidermolysis Bullosa Medical Research Foundation, the volunteer-only nonprofit funder of research for EB, a rare and life-threatening disease of the skin, as it seeks to find a cure. EB is characterized by blister formation after minor trauma to the skin and scarring and disfiguring of the skin and internal organs. Cuoco's manager, Andrea Pett-Joseph, runs the annual Rock4EB! with her husband, Paul, and their 18-year-old son, Brandon, who lives with the condition.
"Even though we had our baby, I had this on the calendar for so long. I'm like, 'We are going to that. We are not missing that.' It's very close to our hearts and it was a huge turnout today, which is amazing," Cuoco shared at the event.
But now that she's is in the early days of motherhood, Cuoco got emotional when asked whether that adds more meaning to the charity and philanthropy work she does.
"Oh my gosh," she said, getting visibly verklempt. "You know, I never thought I would be a mom. So I see these kids out there and I just can't imagine if my kid was hurting all the time, you know? I felt this way before but obviously, you don't know until you have one. So totally take it for granted so there’s not another that gets afflicted by this. We just have to do something."
