I started describing the situation and then realized doing so is a breach of her privacy, so deleted my comment. I did have parental controls on it in terms of the apps she has access to, but had not limited the time spent (my mistake). I wish there was also a way to limit the number of pickups.

No worries that you deleted it, can understand that you want to be cautious with your child:)

Btw, I actually don't have a child so haven't used parental controls, but just found out that they do have an app time-limit setting: https://support.apple.com/guide/iphone/set-up-screen-time-ip....

yeah, I have an app blocker on my iphone to block news websites/apps called Freedom. Essential these days to staying productive - although, don't think this app would work for your child, because it is not very reliable and needs to be restarted every few days.

I use the built in iOS controls for my kids and they are generally sufficient

Just took a look at the app limit features in parental controls, seems really useful:)
