Kourtney Kardashian is set to welcome a baby girl any day now, so how is the reality star spending her final days before giving birth?

Sources told Us Weekly that Kardashian, who is already mom to son Mason, 2, with longtime beau Scott Disick, is trying to spend as much time as possible with her little boy before the new family addition arrives.

"Kourt is home and laying low ... She's been spending a lot of quality time with Mason. She's really focusing on making sure she gets some time in with him before the new baby comes because his world is going to be so rocked!"

Kardashian and Disick announced in November they are expecting their second child together, and from the looks of a new "Keeping Up With the Kardashians" episode, it appears Disick is less-than-pleased that he and Kardashian haven't tied the knot yet.

"The whole reason I had another kid with you is because you agreed to get married," Disick tells Kardashian in the upcoming episode. "You broke the contract -- you broke the deal."

First come babies, then comes marriage? We guess we'll just have to wait and see.
