“Kaley Cuoco and 15-Month-Old Daughter Matilda Make a Splash: ‘We Have a Little Water Baby!’”

Kaley Cuoco is having fun with her water baby!

On Monday, July 1, the actress, 38, shared a video on her Instagram Stories of her 15-month-old daughter Matilda having some pool time.

Appearing to be in great spirits, Matilda displayed a beaming smile on her face as her mother held onto her in a friends’ swimming pool.

The toddler sported a dark blue dinosaur-themed bathing suit along with a matching float that had been placed around her body.

“The swimming continued @amy_davidson pool! She was desperate for me to let go. Time for swimming @ lessons lol,” Cuoco wrote across the video.

“Is that what you wanted?,” she added as she rubbed her daughter’s head. “You want to be a big girl.”

Cuoco, who shares Matilda with her partner Tom Pelphrey, also shared a video of her daughter playing in a water fountain.

Jogging around the fountain, Matilda then ran up to the camera after her mother said, “Hey Matilda!”

“We have a water baby,” the 8 Simple Rules alum’s caption read. “Also when she spots me @tommypelphrey.”
