Paris Hilton is loving toddler mom life.

The mogul mom, 42, shared a video on TikTok Sunday of son Phoenix, who celebrated his first birthday last month, enjoying time in his walker. Instead of strolling around or dancing like in previous videos the proud mom has shared, this time the toddler checked out the I Am Kind board book by Lisa Edwards.

“Where are you going?” a person who can’t be seen in the video asks Phoenix as he takes a few steps, intently looking at his book. “Is that your book? I Am Kind? Aw, that’s so nice.”

Phoenix then walks away and the camera pans over to little sister London, 3 months. While the infant’s face is still not revealed, she can be seen from the waist down, her legs moving around in a cute purple printed onesie with unicorn feet.

“Hi! Yeah, you’re a smiley girl,” they coo at the little one.

On the 66th annual Grammy Awards red carpet on Sunday, the reality star and singer revealed that she will be touring this summer after releasing her upcoming album — and her kids are coming with her!

“The album will be out this summer, and I’ll be going on summer tour as well,” Hilton said during the GRAMMY Live! from the Red Carpet show, adding that she will “definitely” be bringing the little ones.

When asked about how motherhood influenced her music, the Simple Life alum said, “It’s just taken on a whole new meaning.”

“And Phoenix loves ‘Stars are Blind.’ It’s his favorite lullaby at night,” she said. “I love singing to my babies. I love music.”

After welcoming London with husband Carter Reum, Hilton reflected on her newly expanded family of four, telling PEOPLE that she’s “looking forward to just being in my mom era.”

“I feel like it’s my best era yet, and I’m just excited to show the world,” she added.
