As hard as it is to believe, aggression is a normal part of a five year olds development. It’s fair to say that almost every child at this age will occasionally grab a toy from a classmate or kick and yell from time to time. This can be caused by fear; your child might lash out if he feels intimidated by a classmate.
Other triggers have more to do with circumstance s and less to do with instinct. Your five-year-old is adjusting to a new schedule at school and learning a host of new skills. Therefore, it’s understandable that he can easily become frustrated with everything he’s trying to accomplish and end up lashing out. There will also be times when your child will simply be tired and hungry and won’t know what to do about it, so he responds by yelling, hitting or throwing a tantrum.
The good news is that your five year old will outgrow most of this aggressive behaviour. At this age, his language skills are pretty developed and he should be discovering that he can use words instead of fists and feet to solve his problems.
Your child will also will also learn from experience that he gets better results from talking out a dispute than he does from hitting . During this period of aggression, you will need to guide your five year old to an aggression-free approach to life and keep an eye out for deeper issues that could be at play.
