Concern about school

My daughter went back to school last week. I finally got chance to speak to one of her teachers today. 

The teacher advised that Wren had some difficulties today when starting a new subject, ICT. Nothing unusual about this, especially being a Monday. Mondays are not good, usually.

Then the teacher told me that she said to Wren that she had to stop crying and had to be more grown up. Also, on the way home, Wren told me that her teacher told her to stop being a baby. That's when I started getting concerned.

I mean, I'm new this. Most of the time I think that teachers know what they are doing, and do thier best. But today I'm questioning thier professionalism and wondering if I need to call in for a meeting to discuss this? I'm not sure what to say if I do.
