Why Do My Kids Fight?

Why Do My Kids Fight?
Many different things can cause siblings to fight. Most brothers and sisters experience some degree of jealousy or competition, and this can flare into squabbles and bickering. But other factors also might influence how often kids fight and how severe the fighting gets. These include:

Evolving needs. It's natural for kids' changing needs, anxieties, and identities to affect how they relate to one another. For example, toddlers are naturally protective of their toys and belongings, and are learning to assert their will, which they'll do at every turn. So if a baby brother or sister picks up the toddler's toy, the older child may react aggressively. School-age kids often have a strong concept of fairness and equality, so might not understand why siblings of other ages are treated differently or feel like one child gets preferential treatment. Teenagers, on the other hand, are developing a sense of individuality and independence, and might resent helping with household responsibilities, taking care of younger siblings, or even having to spend time together. All of these differences can influence the way kids fight with one another.
