Kaley Cuoco Shares Sweet Snap of Daughter Matilda’s First Time at the Aquarium

The actress documented her 7-month-old daughter's first aquarium trip on Monday

Kaley Cuoco’s daughter, Matilda, is having a whale of a time!

The Big Bang Theory star, 37, posted a cute photo of her 7-month-old baby girl visiting an aquarium for the first time on Monday.

In an Instagram Stories update, a smiley Matilda was seen sporting a yellow bib as she looked at a water-filled glass tank where a penguin swam towards her.

“Aquarium first timer 🥹,” Cuoco captioned the heartwarming snap.

The actress also posted another image — a black-and-white family photo of her and boyfriend Tom Pelphrey smiling together as they posed with their daughter, who sat in between the pair.

“M & D,” Cuoco wrote in the caption, referring to her and Pelphrey, 41, as mom and dad.

Cuoco called Matilda “our angel” in another photo of her as she was held by a friend at the aquarium. The 7-month-old had one hand placed on the glass as a penguin stood and watched her from the other side.

Matilda has celebrated a couple of major milestones in the past few days.

Last week, Cuoco posted photos of the 7-month-old dressed in costume for her first Halloween and, on Sunday, she documented her baby girl’s first time flying on a plane.

In the cute snap, Cuoco held Matilda in her lap on the plane as the little one sported a pair of large headphones over her ears.

"When your baby is perfection on her first flight," Cuoco wrote on her Instagram Stories.

Matilda’s aquarium trip comes after Cuoco spoke to PEOPLE in October about her daughter bonding with another set of animals — her four dogs rescue dogs, Ruby, Opal, King and Blue.

"Oh my God, she got thrown to the wolves literally," Cuoco said at the time. "After she was born, I'm like, 'If this child doesn't like dogs, I might have to send her back. There's no choice. This is your life. This is it.' "

She added, "They have jumped on her. They have crawled across her. We have let them lick her, kiss her. Our pediatrician was like, 'It's okay.' So they love her so much."
