The insider says that Scott moved back to Kourtney's house a few weeks ago. "He has really cleaned up his act and been well behaved. Kourtney is always skeptical about how long it will last, but she has been very encouraged to see how much he has been trying," the source shares, adding that Kourtney's excited to spend the holiday season with Scott and their children as a family.
"They are planning to do everything together over the holidays with the kids and will see what happens," the source adds. "For now, they are taking little steps in the right direction."
Another source confirms to PEOPLE that Kourtney and Scott have indeed been living together again and that they have even planned to welcome another child. The source says that Kourtney "seems very happy" to have reunited with Scott and she "definitely wants four kids" with him.
As everyone has known, Kourtney dumped her boyfriend of nine years Scott after he was caught getting too close with his other ex Chloe Bartoli. The two, however, remained good friends and committed to co-parenting 6-year-old Mason, 4-year-old Penelope and 2-year-old Reign.
They're also frequently seen hanging out together with or without the kids. Over the weekend, the two jetted off to Mexico and enjoyed the sun in Cabo San Lucas. The trip was reportedly planned by Scott to win back the oldest Kardashian sister.
