Kids don't need to be exposed on the internet until they are able to decide themselves if they are okay with it. When that is is up to the parent. I always ask my 8-year old even before I share photos with her grandparents.

It’s more that I don’t know the reason it’s being taken. We have had photos taken by tourists that have sidled up and taken photos and had companies take photos then ask for permission for use in promotion. We felt pressure to accept these after the event, though didn’t.

And then there is privacy.
