Does anyone have experience with a 3 year old screeching? He is 3 in May and he will screech like this from the moment he wakes up to the moment he goes to sleep. He doesn't talk yet.
He will do it when we say no, when we take something away, when ESPECIALLY his 11 month old sister cries, when there's too many people outside, when someone gets on the train and walks into the coffeeshop we are sitting at, when he is tired, etc...
It's constant.
Is this normal?
How do I stop it? I've tried time out, "cooling time" in his room, firmly telling him no, but nothing seems to work.
Thank you
