Songfacts®:

• This song was originally produced by:
  
  Jason "Poo Bear" Boyd, Bieber's go-to co-writer since the two met in Las Vegas at a 2013 party.
  
  Jive recording artist and producer Maejor, whose previous collaborations with Bieber include the Believe track, "One Love."
  
  Nico Stadi, who also supplied instrumentation and programming on 5 Seconds of Summer's Sounds Good Feels Good album.
• Californian DJ Skrillex later reworked the production. He recalled to NME: "The original version of 'Children' was written like a typical EDM song at the writing session we did. It almost sounded like something that Swedish House Mafia could've produced a couple of years ago. I don't mean that in a negative way."
  
  "It was major sounding too, so I reproduced it to be minor sounding and emotional. It's a very simple message Justin is conveying through that song. I can't speak for him, but I think he's starting to grapple with the fact he's a role model for a generation."
