As a mommy of three now, Kristin Cavallari is having to make some sacrifices for her children.

Kristin Cavallari Gives Birth To First Daughter

On Sunday, the reality star posted a new photo of her daughter, Saylor, who was born just one week ago. As Cavallari wears a grey beanie and holds her little girl wrapped in a pink blanket, she looks into the camera and writes in the caption that she had to miss her high school reunion.

Regardless though, Cavallari had a good reason to miss it.

A number of people gave the reality star their support with comments that read, "Ur very blessed Kristin! Very beautiful family!" and "I missed mine as well earlier this year due to having a new baby. Two boys one little girl as well."

Cavallari and her husband, Mike Fisher are also parents to two boys, Camden, 3, and Jaxon, 1. Based on another Instagram photo, it appears that one of the boys might follow in his daddy's footsteps and become a football player.
