I disagree, partly.

You took the pic. The data is yours. You made the kid. The child is yours until they are able to take responsibility for themselves.

You have a responsibility as a parent to not expose them to unwarranted threats, and the internet, writ large, is full of them, so you should curtail the demented urge to blast pics of them on the internet even if you are proud of them.

what about animals? Don't them doges deserve rights on their own data? woof- woof
