The little ones belong to Janelle's daughter, Maddie Brown Brush, and son-in-law, Caleb Brush. "These two are why I am motivated to take care of myself," she captioned the post. "I love watching them grow up and being a part of their lives!" Added Janelle, "Find your motivation and become the best version of yourself 👏❤️." Axel and Evie aren't the only grandchildren within the Brown family.

Sister Wives' Christine Brown Says She 'Adores' Being a Grandma: 'So Rewarding' Janelle is currently spending time with her grandchildren and kids at Disney World in Orlando, Florida. They were also joined by Christine — who previously ended her polygamous marriage with Janelle's husband, Kody Brown, in November 2021 — and her children. "Maddie and Christine and several of the kids joining me," she wrote, sharing a photo of her Evie with Christine's daughter Ysabel. "Yesterday we spent some time at the pool. I just loved this shot of Evie and Ysabel." Janelle's 52-year-old spouse is also married to Meri Brown and Robyn Brown through their polygamous arrangement. Kody's relationship with Meri, 51, is no longer romantic, however.

Janelle previously addressed her struggles with Kody, she said their "relationship is pretty strained" and it'd be "easy to walk away" from it all. Kody, for his part, said that the pair are "not in sync." "We don't partner really well but we actually just are able to have a marriage that's, if you will, lower in attachment," he said during the season 16 reunion. "I don't even know. We're good friends, we get along well. It's more of a, like, just a committed relationship."
