She took a tantrum today because I asked her to zip up because it was minus 2 degrees outside and she wanted to go out in just a T-Shirt and a wide open jacket, she didn't want a jumper on so I said that was ok as long as she put on her jacket.

I only wanted it zipped as a security measure, If she left it open then she would have been frozen and maybe hypothermia.

I zipped it right up and put hood up but she started crying and stamping her feet saying "I do not want it zipped up", my reply was "fine but you stay in instead if you don't leave it zipped", she then ran upstairs, slammed door and lay on her bed for 10 minutes before coming back down and agreeing to my decision.
