My kids fight with each other 24/7.
Cassani Adams: Encourage your children to settle disputes on their own. If they come to you, help them talk through their options. You can also offer suggestions, but let them work out the solution themselves so they learn from the experience.
Dr. O'Brien: Hold a family meeting so your kids can air their grievances and you can mediate. Remind them that they don't have to love their siblings all the time, but they do have to treat them with respect.
Wolf: Give your kids basic strategies for avoiding conflicts. For instance, you might say, "If you don't want your little sister to play with your Legos, you need to put them away when you're done playing with them."
DeMars: It's natural for kids to bicker, but if it persists or gets physical, you'll need to intervene. Since kids often have trouble coming up with solutions in the heat of the moment, you may need to separate them and have a cooling-off period before they can really listen to each other and work things out.
