Pratt stated that her children's book was inspired by her sister Christina: 'We're so close in age — we did everything together — so I wanted to write a children's book that was celebrating the relationship between sisters.'
Pratt also made a funny comment about her brother and he saw her book: 'My brother Patrick posted about my book last night, and he's like: "I'm unclear why this isn't called Good Night, Brother,"' she said with a laugh. 'OK, relax Patrick.'
Here is the goodreads synopsis of the Children's book "Good Night, Sister":
From New York Times best-selling author Katherine Schwarzenegger Pratt comes a beautiful bedtime read, celebrating the power and comfort of sisterhood.
Kat is excited to sleep in her own room--the big girl room--for the very first time. But her younger sister, Tina, is nervous to sleep in their old room without her. So Kat comes up with a plan: she'll give all of her stuffed animals to her younger sister, and every time Tina gets scared, she should hold them close and be reminded of all the wonderful things each animal represents: bravery, creativity, love, and imagination.
But that night, as a storm thunders outside their windows, it turns out that the big girl room can feel a bit lonely. And Kat might be the one who needs the extra support.
With simple, gentle prose, Katherine Schwarzenegger Pratt shares a comforting bedtime story, illuminating the bonds sisters share, and the many ways they are there for one another.
