Why do people use their children's photos as their avatar on the internet?

I don’t get it at all :-/

Why whould you use your baby (1 month years old, for example) as your photo? Remember everyone can see that avatar, all kinds of dangerous people online you don’t know and you don’t want to meet.

I think this phenomenon must be stopped. Parents should protect their children and not to publish pictures of them, especially if they are minors. What is your opinion on this issue?
