Considering how serious Ami Brown's cancer battle was at times, there were many who feared that the Alaskan Bush People matriarch would not see this year's birthday.
But August 28 has come and gone, and Ami is now 55 yeras old.
Rain and Bear joined forces on Instagram to give their mother a series of birthday tributes, as you can see in the video below.
On Rain's Instagram, she and her brother, Bear, give Ami a shout-out on this very special birthday.
"Just want to say happy birthday to mom," Bear says while arm-in-arm with Rain.
"Seriously," Bear says. "It’s awesome to still have our mother around, quite frankly."
Rain chimes in, saying: "Amazing."
Rain then says "Happy birthday, mom!" and Bear echoes the sentiment.
That's all very sweet, but Rain also wrote up a message of her own.
"Dear mommy," Rain writes. "Happy birthday to the greatest woman I know!!!"
We know that Rain is going to turn 16 in a few months, but ti's sweet that she still calls her mother "mommy."
"You inspire me beyond compare," Rain continues. "If I turn out to be anything like you my life would have purpose."
"You listen to me even when I’m having an anxiety attack over the dumbest things," Rain says. "You comfort me just by being in the room."
We should note that Rain has spoken about her mental health before, and also that anxiety attacks are like allergies -- it seeming "dumb" doesn't make it so.
"You mean absolutely the world to me," Rain's sweet birthday tribute message to her mom continues. "And I would be lost without you."
Rain writes: "it’s been an amazing honor to not only know a legend such as you but to call her mommy."
"I can’t wait until we’re both super old ladies together," Rain imagines. "Sipping tea with the grandkids."
"Happy birthday mommy," Rain concludes. "I love you more than the world."
Rain isn't the only one who wanted to put her affection for her mom in writing.
In addition to the video that we've included, Bear also wrote his own message.
"Today was my Moms birthday!!" he writes with his characteristic lack of chill. "I have no words to describe how I feel to still have my Mom!"
A lot of people use exclamation marks on social media to show that they are being friendly in tone. Bear just seems enthusiastic.
"She’s always been there for me! My whole life!" Bear writes. "And I’ve been trying my hardest to be there for her!"
"Thank you everybody!!" Bear says in a shout-out to fans. "All the fans and family’s!! All the production crews we’ve worked with!! Everybody at discovery!"
"Life is too short not to enjoy every moment!!" Bear writes.
That is a very on-brand sentiment for him.
But Bear makes sure to remind people that Ami's birthday is, of course, all about Ami.
"Happy birthday to the strongest and best mother ever!!!"
Bear concludes: "I will never give up and I will never surrender!!"
