The short answer: For children, Instagram is a no — and increasingly that's not just a parenting call, it's the law. Depending on where you live, under-16s may be barred outright (as in Australia) or need a parent's consent (as in a growing list of US states). For older teens (16–17), it can work, but only with Teen Accounts on and a real conversation about strangers in the DMs. The disappearing-message worry belongs to Snapchat; Instagram's worry is who can slide into your teen's messages.
Where the law stands now
Governments are catching up with what a lot of us already felt. Here in Australia, since 10 December 2025, Instagram has to take reasonable steps to stop under-16s having an account at all. In the US there's a federal floor of 13 (under the COPPA privacy law), and a growing wave of states — Florida, Texas, Utah and others — now add age checks or parental-consent rules, though several are tied up in court. Wherever you are, the direction of travel is the same: these aren't accounts built for younger kids. Check your own country's rules — the penalties land on the platform, not on families.
Where it can go wrong (for the teens who can use it)
The thing I'd want every parent to know is that strangers can message teenagers directly. A classic grooming opener is something flattering and plausible — "are you signed to a modelling agency?" — and it lands straight in the DMs. Instagram was named alongside Snapchat in the rise of sextortion, where someone poses as a peer, coaxes an image, then threatens to share it. On top of that there's sensitive content in the feed, Reels and Explore, the endless comparison that's hard on body image, and location leaking through tags.
What Teen Accounts already do
The good news is Instagram has done a lot of the work for you. Teen Accounts are applied automatically to under-18s, and by default they make the account private, restrict DMs to people the teen already follows or is connected to, switch the sensitive-content filter on, add a 60-minute daily reminder, and turn on an overnight Sleep Mode that mutes notifications. There's also a PG-13-style content default. For under-16s, none of these protections can be loosened without a parent approving it.
One honest limit: even with supervision linked, you can't read the DM content. That's why the conversation matters more than the dashboard.
The bottom line: For younger kids, Instagram isn't the right fit — and in more and more places the law now says so too. For older teens, Teen Accounts do the heavy lifting, but check the settings together and keep talking about who's really in their messages.
