Audience
Parents of children 0–6 who use social media

TL;DR

  • ·A young child who says "yes" to "can I post this?" has not provided meaningful consent — the capacity to grasp reputational effects, audience reach, and digital persistence requires cognitive development that arrives in adolescence, not preschool
  • ·Medical information occupies a categorically different sensitivity level from birthday photos; children who cannot yet have a view on their own health history may encounter it in unexpected contexts as adults
  • ·The value of recording and the risks of broadcasting do not have to travel together — keeping a detailed private record and sharing selectively are distinct choices that current tools allow parents to make deliberately

Lead

Posting a photo of your child on social media is something almost every parent has considered. The motivation is honest: sharing a child's growth with family, keeping a record of something wonderful. There is nothing to reproach in that impulse.

But alongside it, a quieter question tends to surface: What will this child think when they find this photo in fifteen years? The child cannot yet grasp the concept of consent, and yet the digital footprint is being laid down now, in their name.

Sharenting — the practice of parents sharing their children's images, information, and daily life on social media — has spread widely over the past decade. A growing body of research is beginning to examine the legal and ethical dimensions embedded in that practice.
