Kourtney Kardashian and children

Us Weekly

The E! reality star has opened up to Us Weekly about how amazing motherhood is and how big brother Mason has embraced his little sister.

"Nothing could prepare me for how hard I fell in love with her," she gushed to the mag. The 33-year-old mother and her boyfriend of six years Scott Disick, 29, and Mason are all adjusting to their new foursome.

While Kourtney expressed that Scott has "improved" as a father, he has yet to change a diaper. Someone needs to get that man a clothes pin and some baby wipes. Chop, chop Scott!
