We're having discipline issues. I don't spank, but trust me, I've wanted to. He talks back like crazy. His daycare is a family member who has a 10 and an 11 year old girl in the house so you can imagine the stuff he's picked up. Time outs don't work. We've taken toys away, he doesn't care. We've tried to explain and reason and I know better, but...Tonight he spent the entire night in his room alone except to come out for dinner. He cried and screamed the whole time. I'm open to suggestions. Please don't flame or criticize, I'm at wits end and I'm looking for positive suggestions and help. TIA.
