Advice: very young or imitate and learn through the actions of adults. His toss indiscriminately is false, the map comment is right. The problem is how the child's attitude. Comments with the proper attitude is correct, but general picking, yelled at dad was wrong, thus the new father General picking again. The universal father picking here is the child's father yelled at behavior.
Mom need objective, explain to your child understand: when I drink alcohol to scatter around the United Kingdom fixtures dad drinking not mastered himself, his mother would comment to me after, his mother kept cleaning the compact housing for cast iron. When the father, I will say to you ". To do so, the child will feel respected, see understanding, we will be more respected than the parents rather than the contrary is disregarded.
Advice: When we told the children: "Do wrong, to apologize and promise to fix" then adults must also be exemplary and do so. If you have not done that, the mother can change them sorry (if things are like that) then ask your child to apologize. Parents can motivate children "as the host, you should be polite, I will advise with him later".=
