"Sister Wives" mom, Janelle Brown took to her Instagram Wednesday, April 10 to announce Garrison's 21st birthday. Garrison, the son of Kody and Janelle entered the world on April 10, 1998. For fans of the TLC show, it's hard to think he's 21-years-old already. It's not that long ago, we saw Janelle and Kody dealing with Garrison as a teen who needed talking to.

Garrison Brown joined the National Guard after graduation at 18-years-old

Garrison completed high school at Centennial High and then enlisted in the National Guard in 2016. Aged eighteen, he hoped for the army, but Kody talked him out of it.

According to TV Shows Ace, "Garrison joined the National Guard two years back and since then he’s been traveling the world a lot. It’s not certain where he lives at the moment, but he seems to be having a blast." Garrison's not very active on social media, so confirmation for "Sister Wives" fans is hard to come by.

Radar Online's always dig-digging around the "Sister Wives" world, and even they came up with just, "he’s been traveling the world. He’s recently posted photos in the United Kingdom, France, California and more." Some fans on the Twitter post that Janelle shared think he's still in the military with the National Guard. He's not saying much though.

His last Twitter post came back in 2016, and his Instagram has a cryptic message: "If I’m not back by dawn, call the president."

Fans react to Janelle's post about Garrison turning 21-years-old

Over on Twitter, fans reacted to sister wife Janelle posting about her boy turning 21. Janelle shared a photo of Garrison relaxing on the sofa with a dog.

She captioned it with, "I’m not sure how the time passes so fast but I now have 4 of my 6 children aged 21 or older! Happy 21st Birthday to my 4th baby." On Instagram, she captioned the same photo with, "Happy 21st Birthday to this cool kid! We love you Garrison."

We don't know if Garrison made it home for his birthday, or if Kody and Janelle threw a birthday bash for their boy.

However, he received many congrats and best wishes from "Sister Wives" fans. Here's what some of them said:

  • @cran**: "You blink & whoa——what happened?"
  • @mrs**: "Happy Birthday to your “baby boy."
  • @Sou**: "I know it just flies and suddenly our babies are adults."
  • @Kim**: "The older we get the faster time goes by. Happy birthday Garrison."
  • @Pau**: "Happy Birthday, sweet young man. Yes, @JanelleBrown117, as a mom of a 30 yr old son and a 37 yr old son, seems like yesterday...our babies."

Garrison Brown on 'Sister Wives' as a child

About five years ago, we saw a scene where Garrison and his siblings went through teen boundary testing.

Janelle said at the time she missed Kody not always being around to help with discipline. When we first met the Brown family in 2010, cute little Garrison said he likes to "ride bikes and hang out" with his friends.

What do you think about Janelle and Kody Brown's son Garrison turning 21-years-old already? Do you think time flies by way too fast?
