I have a waiver for emergency treatment only. It is in case their child should need to go in an ambulance or be taken to hospital and the dr's need to make a judgement call in the parents absence which is deemed by that professional to be necessary to the child's well being, then all responsibility on my part is waivered should things not go to plan. I do not want to be in a position where the doctor asks me for consent. I can not give it and will not give it, so I pass on the responsibility to a doctor if an emergency arises which is time sensitive and would prevent waiting for parents to show up.
