I am a single mom, that has a 2 and half year old boy. I moved in with my parents and my son stays with my mother in the morning when I go to work, but all of a sudden he is hitting my mother and screaming at her and say things like "ugly granny" especailly when I am at home or around and all of a sudden refuses to say good night or kiss her , he screams every time she goes to him or tries to talk to him. My poor mom is very upset and I'm very hurt by this , please can someone tell me how to handle this situation.[Sad]
