My daughter Catriona (8) likes going out during winter, she does wrap up warm, well sort of, she will put on a scarf, gloves and hat/hood and her nice warm regatta jacket but she doesn't want it fastened up but winter here in Scotland can be really cold, sometimes in the minus temperatures so I always zip it then tell her that it'll keep her warm.

Any tips on how I can get to understand why its important to zip up and that its not me being strict?
