I have a 17-month old screamer currently, who I've honestly had enough of. She SHRIEKS all day long, especially whenever she's strapped in to anything- high chair, stroller, etc. The other kids basically walk around with their hands over their ears all day. She's also extremely aggressive, constantly hitting other babies, grabbing toys, pushing and shoving, and last week slapping her 3-year-old sister right in the face. Parents have no discipline and frankly just don't seem to care. Dad does pick up/drop offs and whenever I bring up this behaviour, which is almost every day, he makes a halfhearted 'oh, sorry' and literally runs out the door before I can get more out. I tried to give 2 weeks notice on Friday, and as I was about 3/4 through my speech, he started walking out the door while I was talking, mumbled something about 'sorry it was so loud today' and left while I was still speaking. He knew what was coming, and I think was just trying to avoid it in the hopes that I would lose my nerve. In my opinion, he's lost his right to a face to face conversation. Would it be a cop-out to send them an email giving notice? They're not interested in working with me to fix this, and I can't handle another ten hour day of screaming in my face. Should I try to talk to them again? Or just email and be done with it?
