disabled iphone dont want to lose data

You will need to restore the device using a computer. The process will erase the device. Later you can restore your data from a recent back-up. Instructions here…

If you did not backup your data, you will lose it all your photos and videos.

My 9 year old kept hitting the wrong passcode on one of our iphones. Now it's disabled - how do I get my photos and videos off of it??

You don’t at this point. That’s why you should backup for instances like this.

You have to erase the device and start over.

Backups must occur before catastrophes. After a catastrophe it’s too late.

If you happen to have stored your photos/videos somewhere in addition to the iPhone, you may retrieve them. Otherwise they are gone.
