A traditional wedding cake would need 50 layers to feed each guest at Jill & Derick's wedding.
In this episode, Jessa Duggar (who is not yet engaged at the time of filming) says she will have ice cream rather than cake at her wedding.
Amanda Capps, who is making Jill's and Derick's wedding cake, is a former client of Jill's. Jill assisted in the births of two of Amanda's children: Cooper and Ellen.
Each year the Duggars take enough steps for a person to walk across the United States 7 times.
Now that Jill is 23, the combined age of all the Duggar kids is 293.
The events of this episode take place on May 17, 2014. On this day, Jill Duggar turns 23 years old.
By the time all 19 kids are married, each sibling will have spent more than 300 hours as a chaperone.
When traveling to their hiking destination, the car that Jill, James, and Derick are riding in has "Happy B'Day Jill" written in paint on the rear window.
The Duggars use enough cleaning products to keep seven industrial kitchens clean.
Jessa's boyfriend Ben Seewald has four sisters and two brothers.
If the Duggars ate rolls with every dinner, they would consume 7,665 rolls per year.
While living in Nepal, Derick asked Jim Bob to be a long-distance prayer partner. Jim Bob later introduced him to Jill.
While Jill & Derick will be staying in a larger home after they wed, Josh & Anna's first home was only 960 square feet. The Duggar family home is about seven times larger. The Duggars previously lived in a single-level home where 14 children shared two bathrooms.
According to the show, Jill and Derick's engagement will be four times shorter than the American average.
Family friends, the Hartonos, were visiting the Duggar home during Ben's move to the guest house.
At the dinner that the Duggars held on Mother's Day, Derick Dillard's family and Ben Seewald's family met for the first time.
Jill will be the first Duggar daughter to get married, and Derick will be the first of his siblings to get married.
According to the show, the average wedding has 140 guests. Jill and Derick plan to invite between 1,000 and 1,500 guests.
When the Duggar siblings chaperone dates with Jill and Jessa, they charge $5 per hour for their services.
Before finding out the gender of the baby, the kids took a vote on whether it would be a boy or a girl. Anna participated in the poll, while John David refused to guess, so ultimately, 11 people predicted it would be a boy, and 7 people thought it would be a girl. According to the paper shown on camera, 11-month-old Jordyn was listed as voting for a boy, despite being too young to even talk.
