Hi C.- my advice is a little bit different. I am a nanny to a little girl that would scream like that too. It was so loud and so HIGH that I swear only dogs could hear it. I would look at her and say in a very stern voice "Mary, it is NOT okay to scream like that. I do not like that. Stop." Not yelling at her, not putting her in time out- just letting her know that it is NOT okay. SHe did it a couple more times, and everytime I would crouch down next to her and tell her not to scream. She stopped within a week. DON'T pick her up, then she knows that if she screams you will pick her up. "Mary's" mom taught her how to say "up please" so someone will pick her up, which is so cute and MUCH better than screaming. Good Luck, L.
