I also agree that as much as you want to be outside and it's the parents' fault for not dressing the children up properly, it's pretty heartless to let THREE children cry for over an hour outside because they're cold. Think of the fact that they are smaller than you and so they get colder WAY faster than an adult would. You have to be able to make the call to cut the outside time short even if you don't want to. I also understand that it's not fair to the other kids to have their outside time cut short and that's the message you need to send to the parents who don't dress their kids warmly. You have to be firm with them. Check the bags at drop off and send them back home to get the proper clothes if you have to. It's not right to let the kids freeze to pay for the parents' lack of common sense.
