Hilton Rothschild and her financier husband, 37, will welcome their third child during the summer of 2022, her rep confirmed exclusively to PEOPLE last week.

The couple, who tied the knot in the summer of 2015 at Kensington Palace, is already parents to daughters Lily Grace Victoria, 5, and Theodora "Teddy" Marilyn, 4.

In February 2020, Hilton Rothschild opened up to PEOPLE about the biggest lesson that she's learned from parenting her daughters: "Patience and being the best version of yourself."

She also got candid about one of the most challenging parts of motherhood.

"I think all moms suffer from mom guilt," she said at the time. "I think we could all do better at that and it's important to still do the things you love. Don't let your children completely take over your life. Navigate that balance and find that balance."

"Whenever I do work trips, I'll feel guilty about leaving the children," she said. "But at the same time, I think it's also setting a good example for your children about working on what you're passionate about. I want to lead by example."
