Suggestions?

So we are having a bit of an issue and maybe those in the DOC could give me a hand.  Sugar Bear is now refusing to do a shot a day and a BS check a day as he says "I already know how to do it so I don't need to keep doing it."  We've explained to him the importance as well as helping to establish habits like brushing teeth but these conversations always seem to end in his frustration and tears.  Any thoughts?
