Ipad causing personality change?

[Roundandback]

I recently bought my 8 year old DN a (refurbished) iPad as a reward for working really hard over the last half-term and gave it to her last Sunday.

DN has been staying with me for the last few days and her behaviour has honestly been the worst it has been for months which has got me wondering whether it is possible for screen time to have such a dramatic impact.

She has been argumentative, irritable and just generally unpleasant. The only thing that has changed is the iPad.

Use has been limited but more relaxed than normal due to it being half-term and DN uses it for things like Minecraft, kids YouTube etc.

One of the reasons I got the iPad was so she could use it on the school run to do things like timetable rockstar and night zookeeper but I've already had to take it off her completely!

Am I imagining things or is it possible that screen time can cause such a change?

Any tips managing screen time including length of time, frequency etc? Thank you!

Screen time massively affects my 10 year old. He's more irritable afterwards and triggers poor behaviour. I was the same as a child. Put timers on there if you can, even turn off the Internet if possible.

Triple clicks the button to put it into accessibility mode - it stays on ‘TT rock stars’ for example for the time set and she can’t get off it.

I find my sons behaviour 10x worse when he used his iPad, unfortunately it broke but his behaviour immediately improved when he didn't have it, overnight he became a different child. I'd love to get him a new one because he loves playing games and watching sensory videos but I don't want his behaviour to go downhill again. No advice but you're not alone
