Despite suffering a personal tragedy of losing her older brother earlier this month, Kristin Cavallari is doing her best to enjoy the holidays with her family. While on vacation, the mom of three shared a makeup-free snap during a snow day with one of her sons on Dec. 29.

The photo shows half of the former "Laguna Beach" star's face with a snowy background. The 28-year-old is keeping warm in the cold temps with a fur-trimmed parka.

The hands-on mom also posted a photo of her two-year-old son Camden, playing in the snow. The blonde captioned the angelic snap with, "Snow angel." Cavallari also has a 19-month-old son named Jaxon and a one-month-old named Saylor.

Cavallari gave birth to Saylor on Nov. 23. Just a few days later, her older brother Michael went missing under suspicious circumstances. On Dec. 10, he was found dead in Utah -- cold temperatures were cited as a contributing factor.
