What a great alternative. We believe it's important for children to understand their feelings and how to control them when a situation arises. One of the methods we use is counting to ten (camper counts from 1-10), in English and French to help mediate campers feelings. We use deep breathing while counting until they are able to speak about thier feelings. Simple but effective.
