Anecdotally, I grew up that way pre-digital cameras (I'm 29, my mom is a photographer) and I actively avoid having my picture taken to this day because of it.
I occasionally take pictures, but I make sure to ask "Can I take your picture?" Every. Single. Time. Consent matters. If you're a parent who likes taking pictures, you should do the same as soon as your kid is old enough to understand and respond to the question.
