I was a preschool teacher for 15 years. And I have seen it all,
the best thing you can do for your child is to be consistent.
Sounds like today she was just tired and it escalated into a meltdown.
When my kids were small, they would have hard days too. That is part of testing bounderies and learning to get along with others.
One of my preschoolers was just horrible, his parents would let him kick and hit them. The worst was one day during a parent/teacher conference he picked his baby sister up by the straps of her overalls and threw her across the room.
His parents did nothing to him, just said "no,no! that wasn't very nice"
I marched his little butt over to the time out chair and made him sit there, his parents said he nevers listens to us at home, I wonder why...
He is going into 3rd grade this year and is still always in trouble.
