In an earlier Instagram post, Rumer shared insights into her parenting journey and openly discussed motherhood.

The "Once Upon a Time... in Hollywood" star responded to requests and happily provided recommendations for must-have registry items for first-time parents.

Reflecting on the "mind-blowing" reality that her daughter, Louetta, is now nine months old, Rumer said, "I have had a few friends reach out to me recently who are about to have their first babies and asked me to share a few ideas for must-have registry items to add to their lists here are my favs."

The proud mom included heartwarming photos of baby Louetta in various items, such as a Bumpsuit baby carrier and a play tent with rubber toys.

In a recent episode of "Bumpsuit's" podcast, "Rumer shared her experience with elimination communication, a method that involves recognizing a baby's nonverbal cues for bathroom needs instead of relying on diapers.

Enthusiastically discussing the process with "Bumpsuit" founder Nicole Trunfio, Rumer stated, "It's incredible. It's so validating."

She continued, "We got a little potty. Derek even has a little potty song he plays for her," and then proceeded to sing the special potty song, per People magazine.

Rumer emphasized the natural bodily awareness of babies, stating: "Babies have bodily awareness, so they don't want to poop themselves. We train them out of it by putting them in diapers, and look, there's no way I can catch all of her pees."

"They don't make a cue for it, or maybe they do if you're super, super aware. But I try to get as many as I can and it's awesome. I think it's so great," the actress added.

Recently, Rumer shared observations about her baby daughter, Louetta, noting striking resemblances to her father, Bruce Willis, who was diagnosed with frontotemporal dementia in 2023.

Speaking to People, the "Sorority Row" actress stated that while watching "Moonlighting," she noticed similarities between her daughter and father's facial expressions, especially a discerning look reminiscent of her father.

The star described: "Whenever she's got a stern discerning look on her face, I just see Bruce Willis. My dad – especially on Moonlighting – has this little side smirk, that very [mischievous] twinkle in his eye, and I see that so much in her. We were ecstatic, beyond ecstatic, because we used to watch it literally on videotape."

In a December 19 Instagram Story, Rumer shared the meaningful inspiration behind her baby daughter's name, Louetta Isley. She explained: "I have always loved the name Lou so was thinking of that for both a boy or a girl but then when we found out she was a girl we came up with Louetta."

Rumer continued: "We wanted to give her options. My and my dad's favorite singers are Lou= Louie Armstrong, Etta= Etta James, Isley= Isley Brother."

The name serves as a heartfelt tribute and holds significance, combining "Lou" from legendary musician Louis Armstrong, "Etta" from the iconic Etta James, and "Isley" from the Isley Brothers – favorites of both Rumer and her father, Bruce.
