The Duggar and Seewald families are just 15 weeks away until they welcome a new baby into the mix!

Counting On star Jessa (Duggar) Seewald shared an adorable progress photo of baby No. 2 to Instagram on Tuesday, showcasing her bump at 25 weeks.

The 23-year-old, who is expecting her second child with husband Ben Seewald, posted a side-by-side photo of baby No. 2 next to a photo of their firstborn son, Spurgeon, both at the 25-week mark.

“first – second.#25weeks,” she captioned the photo with arrows pointing to the two pictures.

In August, PEOPLE exclusively reported that Jessa and Ben are expecting their second child, due in February 2017. “We are overjoyed to announce that Spurgeon has a new title in life as ‘big brother!’ ” the couple, who wed in November 2014, said in an exclusive statement to PEOPLE. “We are so thankful that God is adding to our family.”

And although the sex of the baby has yet to be revealed, deciding a baby name is on the to-do list for the couple. “We really have no ideas for names at this point,” Ben said on the TLC series. “So, maybe we will have to get some suggestions at some point.”

Counting On airs Tuesdays at 8 p.m. ET on TLC.
