How do you all deal with winter and the snow and cold? Andrew seems to have a hard time when its cold and seems to get more muscle fatigued after recess. Not because of moving around but because he's not moving much and he's tensing his muscles because he's freezing. Do you all have a temperature that's the cutoff to allow your child out. Our school policy is 0 degrees. That is too cold for him. Any ideas what I can do about this?
