Its really not that hard to do you could literally find a youtuber to walk you through the whole process since it seems you could use some hand holding with tech.
But hey if you didn't want so many chores to do after working long hours maybe consider that before having a child. Not my fault parents didn't think it would be a lot of work.
I mean yeah that would be great if big tech could provide us with more protections and stop tracking everything we do but they aren't going to and governments take their bribes so they won't force them to. So parents are going to need to figure out how to protect their children and adapt to our online world. You can learn these skills and protect your children or not its up to you.
