Hilaria Baldwin doesn't need a manual to stand by her stepdaughter's side.

The reality star revealed how she and husband Alec Baldwin are preparing for his and ex-wife Kim Basinger's daughter Ireland Baldwin to welcome her second baby with boyfriend RAC.

"I'm so excited," Hilaria exclusively told E! News at Page Six's Virtual Reali-Tea Awards on Oct. 6. She recalled of her phone call with Alec earlier in the day, "He's like, 'We have to go visit her before the baby comes.'"

It's the perfect time for the couple to reunite with Ireland—also mom to 3-year-old daughter Holland with the musician (real name AndrĂ© Allen Anjos)—since her birthday is also later this month.

"We'll see if we can go out there and just give her a little TLC because it's hard, especially when you have a toddler," Hilaria, 42, added. "But she is a super mama, and I'm so proud of her."

While Hilaria and Alec, 68, raise their own kids Carmen, 13, Rafael, 11, Leonardo, 10, Romeo, 8, Eduardo, 6, MarĂ­a, 5, and Ilaria, 4, she admitted that some of her husband's tendencies as a grandpa have bled into their parenting dynamic.

"We joke about our age difference, but it makes a lot of sense," the Dancing With the Stars alum explained. "Yesterday, I was having to do tough parenting, and then he was like, 'Just let him have it. Just give him whatever he wants.'"

"I'm like, 'No! This is the problem: You have entered grandpa mode. You cannot bring that into parenting mode. So when I'm talking, you're not talking,'" she recalled telling him. “So, basically, we have to always go back to that."

The Manual Not Included author—who has shared glimpses into her and Alec's expansive family in their TLC show—reflected on watching their life play out on the small screen. 

"It's a wild chaos, but it's a lovable chaos," she beamed. "I feel grateful every single day, even when I'm ready to pull my hair out."

Alexander Rae Baldwin III—the Emmy-winning actor known as Alec Baldwin—was born April 3, 1958, to Alexander Rae Baldwin Jr. and Carol Newcomb. He's the second of six siblings and the oldest brother.

Next came Daniel Baldwin, born October 5, 1960. William "Billy" Baldwin arrived on February 21, 1963, followed by Stephen Baldwin, the youngest of the bunch, on May 12, 1966.

The eldest of the six siblings is Elizabeth "Beth" Baldwin Keuchler, born in 1955 and now a mother of six with her landscape architect husband Charles Keuchler.

No. five of six is Jane Baldwin Sasso, born in 1965. She's married to Randy Sasso and reportedly has two children.

Their father died at the age of 55 in 1983 but Carol—who survived a 1991 breast cancer diagnosis—lived until she was 92. She passed away May 26, 2022, with 25 grandchildren, 14 great-grandchildren and an eponymous cancer research foundation to her name.

“My mother taught me about second acts. And third ones, too," Alec wrote in tribute when she died. "She spent the last 25 years of her life as a fighter and a champion for the cause to which she devoted so much energy."

Alec was married to Oscar winner Kim Basinger from 1993 until 2002.

Their daughter Ireland Baldwin was born Oct. 23. 1995.

Alec married Hilaria Baldwin (née Thomas) on June 30, 2012.

They now share seven children: daughters Carmen Gabriela (Aug. 23, 2013), María Lucía Victoria (Feb. 25, 2021) and Ilaria Catalina Irena (Sept. 22, 2022) and sons Rafael Thomas (June 17, 2015), Leonardo Ángel Charles (Sept. 12, 2016), Romeo Alejandro David (May 17, 2018) and Eduardo "Edu" Pao Lucas (Sept. 8, 2020).

Ireland and musican RAC (André Allen Anjos) welcomed daughter Holland in May 2023.

Daniel shares daughter Kahlea, born in 1984, with first wife Cheryl. They divorced in 1989.

The actor shares daughter Alexandra with second wife Elizabeth, whom he was married to from 1990 until 1996.

Daniel shares son Atticus Baldwin, born in 1996, with fellow Homicide: Life on the Street alum Isabella Hoffman, his partner until 2005. 

Daniel was married to model Joanne Smith from 2007 to 2012.

They share daughters Avis, born Jan. 17, 2008, and Finley, who arrived Aug. 7, 2009. 

Daniel tied the knot with D'Asia Bellamy on New Year's Eve in 2022 and they welcomed son William "Bat" Baldwin on June 1, 2023.

Billy's been married to singer Chynna Phillips—also a member of a sprawling, complicated family—since Sept. 9, 1995.

Daughter Jameson was born Feb. 27, 2000, her brother Vance followed in 2001 and sister Brooke rounded out the fam in 2004.

Billy revealed on Oct. 3, 2019, that Vance had been diagnosed with cancer exactly one year beforehand and had since undergone 28 rounds of chemo.

The teen "stayed VERY positive, focused and kept his life as normal as possible... every single day," his dad wrote. "Kid’s a tough son of a bitch. Sharp as a tack. Funny as hell. Tough as nails. Heart of gold."

Also on the anniversary of his diagnosis, Vance posted to his own account, per USA Today, that he had "been clear" for months.

A reminder the genes are strong among the Baldwins.

"Two years ago today....," Billy posted Oct. 3, 2020, illustrating how far his son had come since his cancer diagnosis. "One of the coolest, toughest kids you’ll ever know."

Baby of the Baldwin family Stephen has been married to Kennya Deodato since June 10, 1990.

They're parents to daughters Alaia, born Jan. 23, 1993, and daughter Hailey, born Nov. 22, 1996.

Alaia wed Pocket Ace Productions founder Andrew Aronow in 2017 and they welcomed daughter Iris Elle Aranow on Aug. 17, 2020.

A certain delighted new aunt gushed on her Instagram Story, "been hard to keep this to myself, my beautiful niece is here and she is PERFECT...Auntie Hails loves you sooooo much."

While they were friends for a decade, it was after a rather whirlwind romance that Hailey wed Justin Bieber in a no-frills New York courthouse ceremony on Sept. 13, 2018.

They further sealed the deal with more lavish nuptials in South Carolina on Sept. 30, 2019, allowing dad Stephen to walk the bride down the aisle and sister Alaia and cousin Ireland to serve as a bridesmaids.

While she swapped her maiden name for her similarly famous married name soon after she and Justin legally wed, it wasn't a decision Hailey took lightly.

"It took some getting used to, for sure," she told Bustle in 2019. "It's definitely strange, it takes adjusting."

Growing up a Baldwin, she added, "I'm very proud of my family name. I come from a great family with a history in this industry."

The couple revealed in May 2024 that Hailey was pregnant with their first child together.

On Aug. 23, 2024, Justin revealed that son Jack Blues Bieber had arrived.

"WELCOME HOME," the singer captioned a photo of the newborn's squee-inducing tiny foot juxtaposed against one of his mom's immaculately manicured fingers.

Justin's mom, Pattie Mallette, wrote on X, "CONGRATULATIONS @justinbieber & Hailey. I LOVE YOU FOREVER BABY JACK."

Stephen reposted the sentiment, adding, "Amen. Congratulations to you and may God continue to bless our family.”
