Jenner posted a photo on Instagram that shows her pushing Stormi in the stroller. The pair appeared to be taking a stroll around Jenner's neighborhood.
"stormi strolls," the star captioned the picture, adding a money-mouth emoji.
Jenner also showed off the stroller in a snapshot on Instagram Stories.
"oh hiiiii," she wrote.
Jenner gave birth to Stormi in February following months of speculation about her pregnancy. The couple took their baby girl on a walk together last week.
"[Travis is] working a lot but spending time with Kylie and Stormi when he isn't," a source told E! News this month. "He misses them so much when he's gone and wants to make sure he doesn't miss anything."
Jenner's sister Khloe Kardashian gave birth to a daughter Thursday following reports her boyfriend, Cleveland Cavaliers player Tristan Thompson, was unfaithful during her pregnancy.
Jenner congratulated Kardashian in a post Thursday on Snapchat.
