The Poosh founder previously opened up about her desire to expand their blended family in a May 2022 episode of The Kardashians.

"The more kids, the merrier. It's more people to love. I am really close with Travis' kids and I love them and it's a beautiful thing," she said during a confessional.

"Travis is a really amazing father. It's one of the reasons that I fell in love with him. He is very, very patient. I think because we've all known each other, it does make it easier to blend our families," she continued. "It's all I could ever want."

After baby Rocky's arrival, Kardashian Barker explained how she changed her clothing choices to be able to spend more time with him.

“Getting dressed postpartum while breastfeeding=throwing on an oversized coat, flat shoes pretty much always, loves leggings, sweats, anything baggy and comfortable aka husband’s vintage t shirts and dickies," the mom of four wrote next to an Instagram Story photo of herself in February.
