I kinda have a issue on my hands. My son is a really good and sweet boy. He does not listen when we go to stores or out to eat? Ha forget it . He'll literally scream and act like I'm hurting him. I try listening games at home and he just doesn't take me seriously. It's so embarrassing, any suggestions that actually work?
