When Sandra Bullock is tucking in her two kids at night, she has a go-to read-aloud: The Family Book, by Todd Parr.

“Everyone will find their family represented there!” she tells PEOPLE of the colorfully illustrated tale, which celebrates diversity.

After a day chasing 5-year-old Louis, 3½-year-old Laila and dogs Poppy and Ruby, Bullock finds herself “asleep by 8:45 p.m.,” she says. “But I’m up by 5:45 a.m., so there’s that. That’s what makes me happy — having so much love.”

She also reveals that Laila, whom she recently adopted after fostering, and Louis, whom she adopted in 2010, share a room.

“It’s pretty amazing to just sit in bed and listen to them on the monitor, how they interact and take care of each other,” she says.

“The most peaceful time of day is when I know for a fact that both of them are successfully asleep,” she adds, “and I can leave their room knowing we have another day under our belt.”
