8 year old son as person

My 8 year old son is the person I chose this week. As I do the judging of him it actuallly feels more like an attack of me. E.g.: he’s lazy cause I’ve let him be, he doesn’t read enough because I hate to monitor 30 min a day as teachers ask us too- so I’ve not stressed it enough and so he’s bad at doing it the way he “should”, he acts like a brat around his grandma and I wish he wouldn’t cause she judges me as having not done a good job, etc. is this okay? I guess what I’m noticing I’m judging both of us – is this okay or should I approach the week with him as my person different?
