Hey ladies. I have a 16 month old who loves to scream when he wants something. he knows 4 signs already and uses them but gets frustrated and screams sometimes. I put him in time out when we are at home but my problem is when we are in public. I don't know how to discipline him when we are not at home. He screams and makes a scene, and i give in, to quite him down. Any advice on how to make the screaming stop?
