“She’s my last baby,” Cavallari, 29, told PEOPLE while celebrating the re-launch of her Emerald Duv jewelry line in West Hollywood on Tuesday. “So I’m just trying to enjoy every second.”
The shoe and jewelry designer says her favorite time of day is putting Saylor to bed.
“Every night I go and I feed her in her room before she goes to bed, and then I rock her,” she says. “She always falls asleep on my shoulder. Every night, I swear I’m in there for 20 minutes just holding her because I really love that moment, and I really love having my little baby. That just totally fills me up every night.”
“It’s a lot of fun, I’ve got to say,” she says. “I’m very into the bows and the dresses — any excuse to get dressed up, and she has on a nice party dress!”
And so far, the 5-month-old has been a very easy baby.
“She is the most chill, laid back, happy baby I’ve ever seen in my entire life,” says Cavallari. “We are so lucky.”
But she believes having a well-behaved baby is karma for having a not-so-easy middle child.
“My second one was not very easy, so we paid our dues with him and now we are very lucky to have such an easy girl,” Cavallari jokes. “Although I know later in life girls are much harder, so I’m just going to enjoy every moment while she’s easy right now!”
