So why the sleepless nights? The new parents have been pulling all nighters with their newborn baby girl, Penelope Scotland Disick, who is reportedly quite the restless tot.
"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,” an insider told Radar Online.
Luckily, Scott is just as willing as Kourtney to help soothe Penelope’s midnight cries.
"When Kourtney was pregnant she told friends that if Scott didn't clean up his ways she would rather be a single mom,” the source said. "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.”
