Ah, they grow up so fast.
It's hard to believe Rachel Zoe's first son Skyler is already 3!
The celebrity stylist took to Instagram over the weekend to share several sweet snaps taken while she and husband Rodger Berman helped their little man celebrate his big day.
"Most magical family day celebrating my Skyler Morrisons 3rd birthday xoRZ #family weekend #livinginstyle #NYC," Zoe captioned a collage that included a pic of Sklyer blowing out candles and another showing Zoe snuggling with the couple's newborn son Kaius, who was born in December.
Another shot showed mother and son in front of a second cake that was topped with some pretty cool sparklers.
A third photo caught Zoe, once again, happily holding Kaius, while posing with good friends Brian Atwood, Joey Maalouf and Dr. Jake Deutsch.
Meanwhile, Zoe recently partnered with Hunters Alley, the new online destination for pre-owned and handmade jewelry, for an online jewelry sale.
The 42-year-old fashionista also has a brand new book out titled Living in Style: Inspiration and Advice for Everyday Glamour.
