Geez. I know loads of people who put photos of themselves as toddlers online deliberately, just because they thought it's cute. I really don't know what's supposed to be embarrassing about a picture of yourself as a toddler. Babies all look the same anyway.
Now pictures of adults as teenagers, that's a different kind of laugh ...
Also, I am very much going to educate my child that in this world things you do are registered on social media and the Internet, and that pictures of her will be difficult to remove. That would, for example, result in that she'd refuse to get on camera during sex. That's for later though.
As for the picture. Because I genuinely thought I stumbled upon child pornography. It had to do with the pose, that nobody else was on the picture, and probably also some kind of discrimination on my side (the kid was Asian) plus the movie Holly [1] having made a deep impact on me.
