Dear mumsnetters, I really need your advice. 
Today DD (5, year1) told me her teacher had yelled at her in front of the class. DD is usually a very quiet and sensitive child, so she felt confused and sad. She recognised she was being a bit noisy when the teacher yelled at her (her words), but not behaving intentionally badly. Still, do you think it's OK to yell at children, especially when they're that young? Should I speak with the her (the teacher) and try to find out what happened?
Just a note, I think it's ok to tell children off and speak things, but I don't agree with yelling/screaming at them. At the same time, I understand grown ups aren't perfect all the time and that working with children can be very stressful, but I don't want this to repeat.
What would you do in my place? Thanks for your advice
