I dealt with 2 terrible screamers for over 4 months - it never got better and ended up causing huge issues with my other daycare children. I had to terminate because they were disrupting the harmony in my daycare and quite frankly it was just abnormal for them to scream, throw fits, and misbehave all the time (I'm talking like 10-20 times a day) ...and it was over not getting what they wanted, being told not to do something, wanting toys the other kids were playing with.....I'll tell ya, it's been a few days since they've been gone from my care and I feel great! The only regret I have is not terminating sooner. Good luck with how you proceed!
