The issues are bit different in treating your child than in treating you. You have the right, unless you are incompetent, to refuse any treatment and the medical staff must honor that. But here you were not making a healthcare decision for yourself; you were making it for your child. While in most circumstances medical personnel should defer to the wishes of the parents in refusing treatment, if in an emergency situation the medical professional concludes that without immediate treatment grave harm or death may result to the child he or she may provide that treatment since there will be no time to argue the matter in court before such treatment is provided.
