Hilaria Baldwin Shares Sweet Video of Newborn Daughter Lucía Playing with Her Brother

The latest additions to Hilaria and Alec Baldwin's family — son Eduardo "Edu" Pao Lucas and daughter María Lucía Victoria — have already developed an extremely close bond.

A recent video shared by Hilaria Baldwin shows her youngest children, Eduardo "Edu" Pao Lucas, six months, and newborn María Lucía Victoria, found it easy connecting and holding hands.

In the caption of the sweet clip, Hilaria, who tied the knot with Alec Baldwin in 2012, marveled over having the pair together for three weeks and how fabulous and beautiful it had been.

"3 weeks of this bonding. I feel so grateful ✨✨," Hilaria captioned the post. "...the waving, the little hand-holding at the end and the baby sneeze ??Edu+Marilu [sic]."

More than 316,000 people have already viewed the video on Instagram. Hilaria also recently uploaded a picture to her Instagram story where she is tandem breastfeeding Edu and Lucía.

During the month of September 2020, Hilaria gave birth to Edu. Then earlier this month, she shocked followers by unveiling that she welcomed Lucía through a surrogate.

By the time his children graduate school, he'll be 85, he joked in March 2019.

In the case of Hilaria's choice to have a baby via surrogate, a source told PEOPLE recently that a woman's right to choose when and how to grow her family is no one's business.

Hilaria and Alec became the proud parents of their oldest daughter, Carmen, in 2013, followed by sons Rafael in 2015 and Leonardo in 2016. They welcomed their son Romeo two years later.

Before welcoming both Edu and Luca, Alec said jokingly in an interview that he didn't want to be a father again. By the time his children graduate school, he'll be 85, he joked in March 2019.

The star also made fun of his finances in a December 2018 interview by saying he couldn't afford to cover his family's hotel bills since his kids like to drink $20 orange juice at the Beverly Hotel.

Meanwhile, Alec's wife gained more publicity back in December when a Twitter thread alleged that she had faked her Spanish roots for the better part of a decade. Her actions were criticized by many.

Hilaria recently confirmed her birth name is Hillary Thomas, and she was born in Boston. However, in her interviews and social media posts, she has spread the notion that her background is different.
