Is this a thing? my 4 year old boy just keeps shouting, not in a temper tantrum as such (although he does do this) just like when he sees his brother he will like roar and get right in his face and just shout at the top of his lungs random things? is this normal ? Also he's started questioning everything, how much things cost and getting cross when they don't cost what he wants them to be. 🤣🥴 I've never had a 4 year old before so this is all new to me!!
