"Showered with so much love at baby boy's sprinkle.🧸💙🍼," Nicky captioned the photos, which ended with her daughters Lily-Grace Victoria, 5½, and Theodora "Teddy" Marilyn, 4, whom she shares with her husband, indulging in sweet treats, and a snap of an adorable girl hiding under a life-size teddy bear.

PEOPLE confirmed in January that Nicky and her husband of nearly seven years were expecting their third child together. They will welcome the little boy in the summer of 2022.

In February 2020, the soon-to-be mom of three opened up to PEOPLE about parenting, sharing the biggest lesson she's learned since becoming a mother.

"Patience and being the best version of yourself — I've learned that with children, it's not what you say, it's what you do," she said.

"If you're going to get upset with your child for screen time or being on an iPad, you yourself can't be sitting on a phone or on an iPad," the heiress continued. "Our children mirror what we do so I think it's very important to set a good example. Be the best version of yourself."
