It's also important to remember that fighting and irritable behavior can be a sign that your child doesn't feel well. Watch your child play. Stay in the same room, play with the children or suggest a new activity. Give positive examples. Choose television programs and bedtime stories that show children cooperating, sharing and playing together peacefully.
Preschoolers are great imitators.
Recognize each child as a special and unique person. Spend time with your child so he won't use fighting as a way to get attention. Your child will thrive with this kind of attention. In spite of your best efforts, there will still be fights. But by laying a foundation for children to resolve conflict when they're young, the number and severity of their fights will lessen as they get older.
