One parenting expert warns increased age limits on social media won't stop kids from being harmed by the platforms.

A new Guardian Essential poll revealed two-thirds of voters supported raising the minimum age for social media to 16 - a step above the 13+ limit for Instagram, Snapchat, TikTok and the like.

Expert Anna Martin says it's also important to develop trusting relationships with kids so they can understand the impact of the technology.

"You're up against it with their peers and everybody else who's using it, which makes it difficult."
