Richie and Disick have been officially dating since last September after initially sparking romance rumors a year ago. In recent months, however, the relationship appears to have gotten increasingly serious.

“It helps that Kourtney now trusts Sofia,” an insider recently told PEOPLE. “The kids are allowed to spend time with her. Sofia likes having them and helps Scott. So far, the kids are giving Kourtney good reports about Sofia.”

“Sofia has shown over and over again that she is willing to stay with Scott even when things are not great — but Scott is doing well lately,” continued the source, adding that the father of three “isn’t really partying” and “spends a lot of time with his kids.”

While a source previously told PEOPLE that Kardashian, 39, still thinks Richie is “too young” for Disick, the couple has her blessing so long as their relationship helps keep him on track.

“Sofia is helping Scott be a better, healthier person,” said the source. “Kourtney feels confident that Scott and Sofia takes good care of the kids. Scott is a great dad when he has his life together.”
