My 2 year old grandson is a nightmare. He throws,kicks, hits and screams for my daughter and son in law all the time. He can't play with other children without screaming. He screams and stands on this toes until they come and get him. They hold him to cook, clean, at dinnertime, their bathroom breaks and just about the whole day. When he is taken out he throws things and quickly clears a table of everything on it. My daughter and son in law feel this is normal behavior and do nothing. They say he is just being a boy. I have tried to let her know how everyone is saying things and she calls me a liar. It has seperated our family. We just had a family vacation and everyone feels they wasted their money and it was the worst vacation. My daughter feels we made them feel uncomfortable. She doesn't care that her son ruined our vacation by her son constant bad behavior. just that we made them feel uncomfortable. Also my grandson's favorite word is snack. My daughter carries a bag of snacks around and for four days her kids ate from this bag. We cooked 3 meals a day but her kids rarely ate anything. My 4yr old granddaughter has gained ten pounds in six months. Please help, I don't know what to do.
