My 5 year old girl have anger issues she doesn’t show her anger in front of anyone like if my younger son doesn’t give her toys then she will react normal but after some time when noone is noticing she just broke the toy of throw it in the dustbin.. she does similar stuff with every other child , is it normal?

A. Okay so I have some questions to ask you did you prepare your five year old child for a younger sibling to come or not because I think what I can feel right now the anger that you mention is basically because of jealousy that your child from the younger one and also you must be feeling left out because you have been spending all the time with the younger one you have to understand the psychology of the older one also I think this is what is related to you need to talk to your child about it
