You may be surprised to learn that these altercations are actually helpful to your children. Through family squabbles, children learn to express their feelings, solve problems, and negotiate. These early lessons help them develop the interpersonal skills they will need throughout life. Focus on the behavior, not the child. Just because Sally looks innocent does not mean she is.
Younger children are just as likely to be at fault for arguments as their older siblings.
When your children start bickering, don't get involved. Turn a deaf ear to tattles and accusations. This allows your children to figure things out on their own. You can offer a lesson on negotiation at a more peaceful time. Although you may have a special relationship with one of your children, you should not show favoritism.
