The app received support for Spanish and French prior to the launch in the two countries today.
Parents can control their child's contact list and kids can't hide messages. Facebook plans to add new features in subsequent updates which will be sourced from parents giving their feedback.
Messenger Kids was first made available in the United States at the end of past year, and has been pitched as a means for parents to let their kids chat with close friends and family in a safer and more controlled environment than other messaging apps.
"A growing body of research demonstrates that excessive use of digital devices and social media is harmful to children and teens, making it very likely this new app will undermine children's healthy development", they wrote.
Unlike the standard version of the service, Facebook says that Messenger Kids does not include ads, and that kids' accounts are separate from standard Facebook accounts.
Appreciation Mission: This soon to be rolled out feature is an interactive guide within the app that will encourage kids to discover and express appreciation for their friends and family. They depict cartoon animals with small slogans such as "Cool", "My BFF", "Great Helper", "Well Done", as well as several other options which are all positive.
Additionally, Facebook is working on what it calls Appreciation Missions, which will appear in the app's Missions section alongside tutorials on how to use various app features. "It's why we engaged in conversations with many groups in the year leading up to the launch and we have continued doing so this year as we prepared to bring the app to families in Canada and Peru", a Facebook spokesperson tells Business Insider.
