I need some advice, please. My 20 month-old son has been exercising his lungs lately by letting out the most ear-piercing screams you can imagine. So much so that it makes my ears crackle,
: (and my husband angry). We've tried immediate redirection. We've tried telling him that it hurts our ears while making a sad face. None of this is working, because, as he's learned from our winces of pain, that this screaming gives him power. The worst part is now he's starting to terrorize the cat by chasing him around the house and screaming.
ETA: When he is doing this screaming, he always has an amused look on this face, and sometimes laughs after each scream.
I really need ideas because we don't want to go down the road of yelling (which makes no sense if we want him to stop jscreaming). For the past couple of days, we've tried just ignoring, and it seems to only be increasing. This is my first child, and I'd be so grateful for some advice. Thanks!
