Jinger Duggar Celebrates 21st Birthday, Receives Tributes From Parents & Siblings

19 Kids and Counting cast member Jinger Duggar celebrated her 21st birthday this past Sunday, and the tributes are pouring in from her many family members.

Instead, she was honored with many tributes from her expansive family.

Like Jana Duggar, Jinger Duggar is often overlooked these days.

Jessa and Jill Duggar have both gotten married, and the latter is pregnant, in the past year, while Jinger and Jana still live almost entirely under the radar.

All four are so close in age, too, making this truly stand out. Jana is older then the two married siblings, in fact, while Jinger is just a year behind Jessa.

In any case, the family couldn't wait to share the love Sunday.

Jessa Duggar shared a cute smiling photo of her sister via Instagram, and wrote, "Happy golden birthday to my sweet sister Jinger! I love you so much!"

On the Duggar family's official Facebook, they shared a photo of her and mother Michelle, holding a sign saying "Happy 21st Birthday Jinger. We love you!"

"Today is Jinger's 21st birthday," they also wrote. "We are so thankful for her love for Jesus and her sweet personality. She is precious to us in every way!"

Jinger makes bug-eyes at the camera. She may be the quirkiest Duggar.

Jim Bob Duggar then posted a baby photo of her, writing:

"Cute little Jinger! Can't believe she's all grown up now ... Today we're celebrating her 21st birthday! Such a beautiful young lady ... inside and out!"

Having lived 21 years, Jessa and Jill Duggar's little sis is now legally of age to drink alcohol, but don't expect them to partake in that anytime soon.

Or at all. Their religion forbids it, cradle to grave.

"We've never like intentionally been to a party where we know there's going to be a lot of drinking," Jill Duggar, 23, told Cosmopolitan earlier this year.

"I've been on the fire department for a few years now, and there's people, young people, 18-year-old girls who have died of an OD. You see the effects."

Whatever works for them. Wish Jinger a happy birthday in the comments below, then take a look at other surprising things not allowed by the Duggar family ...

9 Things BANNED in the Duggar Family

1. Dates Without Chaperones

The Duggar parents often accompany their children on dates in order to maintain their "accountability" and "keep things from going in the wrong direction," per Jim Bob. The girls are fine with this, as being alone with men puts them in grave "moral danger." When the parents aren't available, their older siblings will often tag along, making every date a group date and a family affair.
