It's not easy post about Year 2.
Once all the kids are talking about Minecraft/Roblox/YouTube etc I think you have to allow it. And keep boundaries that feel comfortable to you.
I try to allow it as one of a wide variety of things we do. My 7 and 9 year old have had tablets for 2 and a half years (due to what the school required of them during lockdown which I now disagree with in hindsight). Reading, swimming, walks, cycling, audio books, podcasts, art, junk modelling, lego, play with toys, climbing, fun days out, learning an instrument are all interspersed with screens. I have to put in 100% effort here. I also only allow documentaries Mon-Thurs....the flashing lscreen and loud noises of some of the cartoons are a nightmare. I also hate what I call "shouting American youtubers" who seem to be mostly young guys doing loud pranks.
Also, neuro diverse children can use tech to self regulate and gaming can often allow them to socialise in a way which bypass their social and communication difficulties, so be prepared for that too.
Personally, the last few weeks of the summer holidays have been too screen heavy for my liking, creating moodiness and tempers in my children. We have reined it back in over the last few days and it has made a huge, notable difference.
Some boundaries I fully intend to keep as they become teens : no tech in the bedroom, turn off at an appropriate time we agree on every night.
As a teacher in secondary, I have seen many a lovely twenty come unstuck with yniwise photos sharing/SM usage or choices.
