How can i improve my relationship with my child? he wants to eat junk and not study. and when i try to enforce , he thinks i'm too strict.

Parenting vs friends: You are his parent - stop trying to be his friend right now. Too bad if he thinks you are too strict - that's life, and it's better he learns it form someone who loves him than go into the real world and think everything will go his way. Don't buy ANY junk food to have in your house. What he eats away from home you can't control. And if he doesn't study, he doesn't do anything else either - period

Need more info.: Parents can't always be buddies, but it is important to choose your "battles" and then enforce. Some junk food is ok, but limit what you buy. Passing or failing in school? Find time to have fun times with your child, and then set reasonable guidelines for study & removal of privileges if not kept., and then enforce. If continued problems, a counselor may help.

Starting Over: I doubt that many of us physicians think we are 'experts' on parenting. We all struggle when it comes to this vital role. But, remembering who is the parent is always a good place to start. Loving firmness. Explaining the rules. Asking and then listening for a child's opinion. Not prejudging their opinion. Sometimes explaining what can slide and what cannot slide.
