Hailey Bieber Reveals Her and Justin Bieber’s Son Jack’s Favorite Word

“He’s been saying, ‘Baby, oh, baby, oh,’” the 31-year-old said as she mimicked her son’s voice. "Literally in the last two days."

Plus, also much like his dad, the toddler has started to take an interest in sports.

“He’s running,” she shared. “He’s kicking a soccer ball. He’s throwing a soccer ball. He’s into all of it.”

Hailey’s motherhood era has been filled with fun surprises, especially as her son has gotten older and her anxiety surrounding parenting has faded.

“When they’re so small it’s a lot scarier, but even so I was a lot more relaxed about everything than I thought,” she said about her motherhood experience. “Because I realized you just figure it out as you go. Like every single day you’re figuring out how to be a parent as you go, and you’re learning as they’re learning.”

"I think it’s just the coolest thing to watch a little person become their own little person,” she added. “Like I’m watching him get his personality and see what he’s into.”

And while Hailey’s having fun raising Jack, expanding her family isn’t out of the question.

“I’m taking it one kid at a time,” she told Jake. “I definitely want one more. I’m not like in a rush, I definitely want one more. Maybe I'll have three. I don't know, I really don't know. I'm just taking it one day at a time.”
