How have you lasted a whole month with a screaming child? Does he scream non-stop?

I had a boy last only 3 days. He literally screamed from the second mom dropped off until I called her at 2 to come get him because I couldn't stand it any longer. The other kids would cover their ears (his scream was so high pitched it hurt the eardrums). He wouldn't eat or sleep, just scream. I lasted 3 days and told mom it wasn't going to work. I was already the 2nd daycare. The first one only lasted 1 day. He managed to transition into his 3rd daycare ok.

I have had kids who are hard to transition but never had an issue with a child screaming like that one boy. I don't/won't hold a child all day either. I have too many things to do. Also it isn't fair for the other kids to not get their nap and have to listen to a screamer the whole day.
