Strung Out

All I hear is shrilling screams from across the house, I'm trying to shut them out. Wits end is where I'm at. I've only got one child but if I could record her right now you would swear there was a room full. I'm shocked social services hasn't knocked on the door yet (the new disturbing trend)! The funniest thing she has said,"I'll be good in a minute!" HA! Minutes up, still shrilling screams. T~ said she's just tired but these tantrums are becoming more often! How do you control them? Where to start? AHHHH!!!
