Is it normal for a 5 year old to scream and throw things?

He goes to pre-school, and I notice when he is home he screams a lot and throws his clothes and toys. <br><br>His mom died when he was 9 months old. Is this normal? I don’t know what to do about it. <br><br>His mom was doing fine and died of a heart attack. I was so in shock for so long and he was so young. I haven’t really figured this out yet.
