'Exhausted' Kourtney Kardashian & Scott Disick Pulling All Nighters With Their Cranky Baby

By Adriane Schwartz - RadarOnline.com Reporter

After endless fights between Kourtney Kardashian and Scott Disick about his all night escapades, Kourntey's baby daddy is home, but he’s still pulling all nighters, RadarOnline.com is exclusively reporting.

Their new baby girl seems to like the night life, just like her daddy, and has been keeping the reality show couple on their toes, and out of their bed.

"When the baby was first born they came together, Kourtney demanded he help and surprisingly Scott came through," a source close to the family told RadarOnline.com

"Their first baby was really easy so they weren't prepared for this, she's been keeping them up all night crying so they have both been on edge.

"When Kourtney was pregnant she told friends that if Scott didn't clean up his ways she would rather be a single mom.

"But, he appears to have really stepped up to the plate, much to everyone's surprise. Kourtney and Scott are totally frazzled though, they have been losing a lot of sleep and that is stressful on any couple.

"No one can believe it, but  Scott has actually decided to do the right thing, for once!"
