Screaming?!

Hey? Are any JJ's out there screaming?!

I mean like screaming to communicate? Most of the time it is while he's in his high chair and he's signaling to us that he's done or he wants his drink or sometimes that he wants another bite if it's something I'm feeding him. It's a high pitched squeal and it's horrible!

Sometimes he does it other times too - but mealtimes are the worst. He's also taken to just yelling his 'words' a lot too...

Anyone else doing this? What is the best approach to deal with it? Do you ignore it? Tell him no? I'm lost...

Thanks!
