rule of 3 for young

Hey,
When my 5 year old enters the rule of 3 and has earned either a major maintance or lost of privilege for 3 hours, he then will not choose to do them and I tell him he wont have any privileges until after the major maintance. BUt he still will force himself into my play wiht my 3 year old and I in our fort playing or playing ballv( he will take the ball away so we can't with it), reading a book. DO i just let him tag beside us until he chooses to do his MM? THe only thing I can really enforce is he doesn't get any special food at meal times, no snacks. We only do screeens and see friends 1 or 2 times aweek so those aren't always options I can take away. Do I just let him tag along until he chooses? I have locked him in his room before which I dont think you would approve, it works, he has to stay in there until he chooses to do his major maintaince, I want to do the best thing for him, but what do I do?

IF he it is a lose privelege for a few hours and he ahs to do chores… does he need to have a happy attitude for 3 hours while doing those chores? And if he doesn't have a good attitude and complains does his 3 hours start over? What if he is working really slow at the jobs like a 5 minute job turns into a 30 minute job?

Also my 5 year old when he enters the rule of 3 he becomes extremly needy, helpless (like cant stand up unless I help him etc..) and begs to be right by me or else he will just cry and cry. I want to have healthy attachment with him and for him to be secure and feel loved but what do I do when he is hanging on my arm in these situations?

Thank you !! Your method has been an awnser to prayer to me and has changed my household for the better with so much peace! I am so thankful!!
