But it isn't that Jill is expecting another baby already.
Derick's tweet on Friday started a rampage of baby rumors for the couple, whose first baby, Israel, is now 5 months old.
Exciting things are happening in our family. Keep a watch for an announcement coming soon to http://t.co/fOjfUIbXoJ— Derick Dillard (@derick4Him) September 17, 2015
And, while it turns out the news does have to do with buns in the oven, none of those belong to Jill again just yet.
Rather, Jill is officially a midwife.
"I am so proud of her for her diligence, perseverance, and hard work to see this long road through to its end and reaching her goal of becoming a CPM," Derick explained on the Dillard family website.
"Jill has been very disciplined and sacrificed a lot to get to this point," Derick added. "So much so that I don't have the capacity within this brief blog post to give all the details to do it justice."
But he did say that she had "sleepless nights with long labors" while also "being on call for multiple births at a time."
Jill plans to use her new, official skill to help their work in Central America, where the couple has been spending the past few months doing missionary work.
"Now begins the fruit of that labor, that is, having a valuable skill and 'tool in the tool belt' to use for the furthering of God's Kingdom," Derick explained.
And though the couple's baby news wasn't about expanding their family just yet, people still aren't convinced that it isn't going to happen soon.
"I still think: she is pregnant again!" one Instagram commenter said.
Another added, "She looks pregnant."
