AceShowbiz - Kaley Cuoco has shared a new video of her kissing her newborn daughter. The 37-year-old "The Big Bang Theory" actress, who welcomed Matilda with her actor partner Tom Pelphrey, 40, eight weeks ago - called her the "sweetest little girl" in a caption on a clip of her singing to and craddling the new arrival.

In the black-and-white clip posted on her Instagram Stories, Kaley was seen her talking to and nuzzling her daughter to the soundtrack of "Over the Rainbow". "We missing daddy! @tommypelphrey," she captioned while also including a picture of Tom cuddling the little girl.

Tom told People about loving life as a new, first-time dad, "It's amazing. It's heaven, it's challenging at times. It's the most beautiful thing ever. I'm so grateful to have a partner who I love to do it with because just two days with a baby in the house and I think of parents who are raising kids by themselves, and I don't even understand how they do it. My respect for single parents has gone through the roof."

When he was asked what had surprised him most about fatherhood, Tom added, "It really has been surprising to me that it feels intuitive. There's just something about how to hold her and how to burp her and intuiting what she wants sometimes when she's upset."

"That surprises me because I've been around a bunch of babies and I have nieces that I love that I was pretty comfortable with. But for the most part, it was like, 'Oh, don't hand me that baby. I don't want to break it.' And it hasn't felt that way at all with Matilda. So that's been a surprise in a good way."
