The former Big Bang Theory actor - who has 18-month-old daughter Matilda with her fiance Tom Pelphrey - has hit out at critics of her parenting style and insisted she felt under the microscope even before she gave birth.

"Every mom, I can guarantee, is doing the best they can," she told E! News.

"Look, everyone's got something to say about everything. There's no change before I had kids, to having kids, to where I am in my life.

"It's just this business, it's this life. It is what it is. But yeah, we got to stop at the shaming."

The 38-year-old actor insisted her daughter is "the happiest kid in the world" and surrounded by "love".

And she explained that every child in the world was "so different", which meant parenting was not a "one size fits all" approach.

Cuoco announced the birth of her daughter via a social media post in 2023.

The actor wrote on Instagram at the time: "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. (sic)"
