Yesterday was Kristin Cavallari’s younger son Jax’s birthday—we totally forgot. He is now one year old. Here are some facts about Jax:

Full name: Jaxon Wyatt Cutler

Astrological sign: Taurus (w/ Capricorn rising)

Likes: “ice cream” made of cashews—allegedly

Dislikes: unknown

Temperament: colicky (like Kristin was as a baby)

Vaccinations: n/a

Kristin wrote to Jax on Instagram yesterday, “Well, that was the fastest year of my life. Happy 1st birthday to my little baby bull! I love u with all of my heart, wild man.”

Only 364 days until Jax’s next birthday and 397 days until Kristin’s debut book hits shelves.

This has been 500 Days of Kristin.
