I have come to realize that kids tattling etc is never going to end lol. I just keep redirecting them, with very little attention unless it's needed. BUT- One thing I cannot stand is whining! So, for that- I either ignore them until they talk nicely, or if they don't get the hint, I tell them that I don't want to hear a whiney voice I want to hear a sweet voice/big kid voice. Sometime's I say that kids who while don't get answered lol. It took a while, but my one biggest whiner came around really well, and almost never whines anymore! Persistence is key I think. Way easier said than done though Good luck!!
