I entered the wrong date when creating the PSN account for my son and I want to correct it. It is made younger, not older, in order to answer this question right away. I found a link where the date can be changed, but it can't make it younger (!) Than 16 years old.
Read this through, maybe it will help: https://www.trophies.de/forum/thema/165211-einmalige-m%C3%B6glichkeit-das-geburtsdatum-in-eurem-psn-account-zu-%C3%A4ndern/
Thank you - this is exactly the link I already had and can't select a date AFTER 2004, so only 16 years or older. But he's only 13 …
There also seems to be a place where I can only adjust my own birth date, then it would make sense. But what if, as a parent, I want to adjust the age of a child?!
I can't really help you with that. Have a look at PlayStation Support, you might find something suitable here. https://www.playstation.com/...e/support/
