Now that the news is out about the gender of Jill Duggar-Dillard's baby, she and hubby Derick Dillard is already prepping for the little boy's birth by completing their baby register at the local Walmart.

Basing on the list that the couple picked for their upcoming son, both Jill and Derick chose a range of baby necessities as well as several splurges for the parents.

Some of the typical baby registry items that the couple picked out for their firstborn include diaper rash ointments, cotton swabs, basic baby care kits, reusable nursing pads, flannel blankets, infant changing pad cover, fitted crib sheets, infant bather pad, bibs, as well as lots and lots of baby diapers.

However, there are several items that were surprisingly included in the list, such as cases of Gatorade G Orange Sports Drink, fitness Stability ball, and even a pair of sunshades. These items are undoubtedly for the parents and not for baby boy Dillard.

The reality show stars announced the gender of their baby Tuesday, after the couple went to their first ultrasound trip, with the other Duggar kids tagging along, namely 16-year-old Joy, 13-year-old James and 7-year-old Jenny.

Jill, the 23-year-old mommy-to-be, admitted that she thought that she's carrying a baby girl at first. Meanwhile, the 25-year-old future dad told People that he was just praying to have a healthy baby the night before the scheduled ultrasound. He also shared his excitement about having a boy as their first offspring.

"As a new dad, to have a firstborn son to be our first child and be the leader of his siblings, it is very special," Derick stated.

Meanwhile, their popular TLC show "19 Kids & Counting" will finally feature their highly anticipated wedding.

The Oct. 21 episode already showed the Duggar version of a bridal shower, where Jill was surrounded by the entire family as well as the kids that she helped deliver as a midwife.

For next week's episode, the big wedding celebration for Jill and Derick will finally be seen by the fans. The very first kiss between the couple will also be seen in this episode.

The much awaited Jessa and Derick wedding feature of "19 Kids & Counting" will be shown on Oct. 28 on TLC.
