Scott Disick is ''taking care'' of Kourtney Kardashian as she prepares to give birth again.

The couple, who have been arguing over the 31-year-old entrepreneur's drinking and partying in recent months, are reportedly in a much better place ahead of the arrival of their third child later this month, as there has been a noticeable change in Scott's behaviour.

A source said: ''For the first time in a long time, Kourtney said she has nothing to complain about when it comes to Scott.''

Scott checked into rehab for five days over the summer after being hospitalised for alcohol poisoning, but is now attempting to get his life back on track for the sake of their family, including son Mason, four, and daughter Penelope, two.

The insider told gossip website ''Even though Kourtney is moody, Scott has actually been good to her and to the kids this past week.

''He is taking care of her and she says she is content right now. She even referred to him as her sweetheart!''

Scott recently admitted he was convinced he was going to die when he nearly overdosed on alcohol and sleeping pills in June and Kourtney, 35, threatened to leave him unless he sought treatment.

She said on their show 'Kourtney & Khloé Take The Hamptons': ''You're either going to be away for a month - or be away from them [the children] forever.''
