Janelle Brown Showers Son Gabe with Birthday Love as Rift with Dad Continues to Play Out on “Sister Wives”

"Thank you for being the son who is always checking in on his mama, who feels deeply and has the tenderest of hearts," Janelle Brown shared in honor of her son Gabe's 22nd birthday

Janelle Brown is celebrating her son’s Gabriel "Gabe" Brown’s 22nd birthday amid the long-simmering strain between him and his father Kody Brown.

On Wednesday, the Sister Wives star shared a montage video of Gabe shoveling snow, cuddling a dog and taking in the great outdoors.

“Happy Birthday @gaberown! I hope your next year is better than ever,” she captioned the clip, set to a melodic version of "Happy Birthday."

She continued, “Thank you for being the son who is always checking in on his mama, who feels deeply and has the tenderest of hearts.”

The birthday message comes after the 54-year-old mom shared concerns about how sons Gabe and Garrison Brown, 24, were handling their strained relationship with their dad on the latest episode of the TLC series.

“Me and Garrison are at odds with my dad, because when we expressed our discontent at how things were going with COVID, I was met with just a wall,” Gabriel said early on in Sunday’s episode. “And there was no line of dialogue. I think that that is what really drove the wedge between us.”

In a later confessional, Janelle said, “I have worried about my boys’ mental health. Gabriel feels everything very, very deeply. But he’s also the kid who doesn’t say anything."

Of Garrison, she added he "just seems angry or sadder, like, he’s not as happy-go-lucky as he used to be.”

Christine Brown weighed in on the changed family dynamic, noting, “My kids are more used to Kody not being in their life. He just wasn’t around as much.”

“But he has been around Janelle’s kids," the 51-year-old continued. "For them, this is just a lot more devastating than it has been for my kids.”

In an exclusive interview with PEOPLE, Kody admitted to feeling "powerless" when it comes to seeing eye-to-eye with his older children and acknowledged their relationships have become strained.

“Your relationship with your 10-year-old or your 5-year-old or your babies is very different than the relationship you have with a 15-year-old, a 20-year-old and a 25- and a 30-year-old. It's very different,” he said. “I didn't have any power in my household to say, ‘These are the rules.’”
