Anger issues

my son, like any other kid throws a fit but, sometimes he hits himself or throws things or hits me back and his almost one yr old should I be worried or is this something that all baby's do

    Like Laura said, they don't really know what's going on and don't know how to tell you what's wrong or making them mad. Be patient with him help him find words.. I always tell my kids "I know you're frustrated, but screaming and throwing things are not good, show me what's wrong." Usually i can piece together what's going on because even my two older toddlers that talk can jumble their words when they are excited or angry making it hard to understand.
