My son is 4. He's always been pretty laid back and well behaved. Terrible 2's were not terrible at all. and until recently he's always listened to me and his father. One thing has changed. His father has moved from his apartment to down the street from his sister. She has 2 kids. my son is now terrible for 2 days after he drops him off. I'm thinking he's over tired and picking up habits from his cousins?? Im not exactly sure if it's the move itself or the other children making him act this way. His father and I have argued many times over keeping him on a schedule, but my son always bounced right back. Does anyone else see this with their children? any suggestions? I hate having to yell at him or put him in the corner right when he comes home from his fathers. I just wanna hang out with him because I didn't get to see him in a few days. AHHHHHH!!! It drives me crazy!
