For his big day, Phoenix was dressed in a pair of tiny blue overalls, a plain white T-shirt and pink Converse sneakers.

In one adorable photo, Phoenix looks enamored with a stuffed German Shepherd lying in front of him and his mom.

Phoenix received a ton of love from Paris’ Instagram following, including her father Rick Hilton.

‘I can’t believe Phoenix is a year old! I love that guy I love you,’ the businessman wrote.

Paris penned a gushing tribute to her son on his actual birthday, which was Tuesday, January 16. It included series of sweet snaps from their first year together.

‘One year ago, a beautiful angel baby entered our lives, bringing so much love and happiness,’ she began.

‘My precious little one, you are more than a dream come true,’ the reality TV personality — who shared a gracious response to her fans’ concern about her son’s crib being overstuffed with blankets last week — continued. ‘You make my life complete.’

On motherhood, she added: ‘Every day with you is a priceless gift, and I’m endlessly grateful to be your mommy.

‘Celebrating your first of many birthdays, Baby P,’ she wrote. ‘Here’s to a lifetime of laughter, love, and wonderful adventures with our cutesie crew! Happy 1st Birthday!’

The cover photo for her adorable photo album showed Paris in a pink fur coat as she cradled a then-infant Phoenix on their private jet.

She then shared a picture of Phoenix bundled up in a onesie and knit hat as he sat on the couch, beaming, in front of a portrait of her on the wall.

She also posted a photo of herself looking tenderly at her infant son as he held him with his back to her chest.

Another two snaps in the series showed Phoenix, dressed in a doctor’s costume in onesie form, as he sat on a teddy fleece chair in his nursery.

Surrounded by stuffed animals and toys in the pictures, he posed and smiled sweetly at the camera.

The entrepreneur also shared a photo of Phoenix riding a toy unicorn as Hilton sat on the ground next to him and stared lovingly at him.

Another snap showed Phoenix sitting in a carseat as he sported a pair of sunglasses and a baseball cap.

Hilton shared a picture of him with her in the recording studio as seen in her latest TikTok post — in which she announced she was working on her sophomore album.

She also posted him in another costume onesie with a cowboy hat on his head.

The last addition to her post was a clip of Phoenix cooing as Hilton fawned over her ‘cute’ and ‘handsome’ boy.

In the carousel post, she only shared photos of baby boy Phoenix and herself but none of Carter, nor their second child.
