Stories before sweet dreams! Kourtney Kardashian revealed the bedtime books of her three children, Mason, 5, Penelope, 2, and Reign, 1 month, on Monday, Feb. 9, along with her own.

The mother of three, 35, posted a photo to Instagram of the titles, including two monster-themed books Working Mummies and The Monster at The End of This Book. The largest copy of the three illustrated books was Walt Disney's Peter Pan.

Working Mummies, written by Joan Horton and Drazen Kozjan, is a book about working mommies who just happen to be... mummies. The playfully titled tome was written for children whose parents "disappear" to work every day and return many hours later.

Bed time.

After sharing her kids' choice of nighttime reads, the reality star then shared her own personal nighttime routine with fans. "Goodnight," Kardashian wrote alongside a photo of her essentials, including classic Jane Austen novel Emma, tucked away on a luxurious fur blanket. "My favorite face wash oil, sleep mask, a book, blanket and some dry shampoo out for tomorrow morning."

Kourtney welcomed her third child with longtime boyfriend Scott Disick last December, naming the child Reign Aston Disick. After giving birth, Kourtney shared with fans that she's been taking placenta pills — which she memorably described as "life changing" — and has been waist-training to slim down her physique.

Meanwhile, Disick, who made headlines last month for partying, updated Us on his life with Kourtney and their kids. "It's my third time so it's kind of a charm," Disick told Us. "I think I kind of know it by now. The first one was scary. The second was less scary. The third one was, okay — I got a whole team over here."

The proud dad added that his oldest two kids Mason and Penelope were handling Reign's addition to the family well.

"I really would have thought the other two would have been jealous," Disick told Us. "They're so accommodating and welcoming — I don't think I would have been that way if I had a sibling. I can not get over how much affection the other two have shown the baby. It's like — thank God, knock on wood."
