I try to teach my 5yo to knuckle himself he quits after just a couple seconds and says "I can't". So today when I told him to try and wouldn't I took the car seat out and brought it inside with him in it. I told him he will stay in it till he gets out himself. (Even though I will probably let him out after too long) He got the chest buckle without issue. He has been sitting for 10 mins whining and saying he can't undo the base buckle. I feel like I might be an asshole for how I am choosing to do this but shouldn't he know by now? I have watched late 3yos and 4yos get in and out of their seats without issue. At least I took him out of the car. I know my father would have left me in the car to figure it out. He opens the car door from the outside and inside without issue. He has basically destroyed a controller button mashing. He can control the backhoe attachments better than most adults I have seen. Am I the asshole for expecting this of him? Or for how I am going about it?
