Back in April, Jenner uploaded apost on her Instagram Story, where she first gave fans an insight into her weight gain — and subsequent weight loss — following her second pregnancy.

“Gained 60lbs again this pregnancy,” Jenner wrote alongside a black-and-white shot of herself walking on a treadmill before she detailed that she is currently “down 40lbs 🙏🏻.”

In an April interview withUSA Today, Jenner revealed that she and the “Highest in the Room” rapper “haven’t legally changed his name yet.”

“We’re in the process, so it just wouldn’t feel right to share anything when we don’t have an official name,” she said at the time. The star also said that she “knew the second I signed the birth certificate that I was probably gonna change his name.”

“It just didn’t suit him,” she explained.

A source previously told PEOPLE that Jenner will “share his name when she’s ready.”

“Kylie and Travis liked Wolf, but after getting to know their son, they felt like the name didn’t fit him. They wanted to choose the perfect name that they both loved,” said a separate insider.
