Since the Keeping Up with the Kardashians reality star, 20, and the rapper, 26, welcomed their daughter on Feb. 1, they have grown closer together as they continue to raise their 3-month-old.
“Her relationship with Travis couldn’t be stronger. Having a child together really changed their relationship for the better,” a source tells PEOPLE about Jenner, who has been dating Scott since April 2017.
“Kylie spends so much time with Stormi. She’s super proud to be a new mom and is very hands-on,” the source adds. “She’s more hands-on than he is, but he still definitely does his fair share to help wherever he can.”
