Part of Facebook CEO Mark Zuckerberg's nighttime routine with his two young daughters is coding before bed, his wife Priscilla Chan told The Times of London in an interview published Saturday.
Chan, who shares daughters Maxima, 5, and August, 4, with Zuckerberg, said the couple likes to split their parental duties, with her getting the children ready for nursery school in the morning and Zuckerberg putting them to bed at night.
When asked about Zuckerberg's bedtime routine, Chan told The Times: "Sometimes they will read books together. Sometimes they'll code together."
"Mark has been doing that with August since she turned three," she told The Times.
Zuckerberg, who is Jewish, also does a little bedtime prayer in Mandarin Chinese with his children, Chan, who is of Chinese descent, told The Times. Zuckerberg reportedly taught himself Chinese and in 2014 conducted a 30-minute Q&A entirely in the language.
Earlier this year Zuckerberg shared a photo of his daughter August's coding sessions in a Facebook post.
"I just want to say that teaching a kid to type is one of the greatest tests of patience I have ever experienced," he wrote.
"August types at literally 1-2wpm [words per minute]. And when she gets a few letters into a word and then makes a mistake and accidentally presses delete three times instead of once and then has to retype the whole word, I feel like I'm just going to lose it."
The Times article was published three days before Insider's Rob Price and Becky Peterson reported that the billionaire couple was being sued by two former household employees over allegations of harassment and discrimination inside their family office, which manages their lifestyle needs.
