No child left out in the cold

I have personally found out from the school that all it has to be is only a small very cold 6 degrees outside and they make the children go outside for recess not only that in the morning when the doors open for the children to come inside the preschoolers have to wait outside for 10 minutes before they can go inside so my complaint is children should not have to go outside and hide in the slide tunnels because they're so cold even with their jackets and snow pants my daughter hides in the tunnels during recess and it's wrong
