DH and I are taking our first vacation away from Marah Jade. We are going to be in Las Vegas for 4 days and I am not sure what to do for MIL in case she has to take Marah Jade to the doctor. Chances are if she does have to take her it will be urgent. I was going to leave DD's medical card but am I supposed to leave a letter or anything as well? I don't want my MIL to have authority to make certain decisions about Marah Jade although I understand in an emergency you gotta do what you gotta do. My biggest concern is if she gets hurt they may want to give DD a tetnus shot which I do not consent to. Would she have authority to authorize everthing or would the doctors just take over? SHould I leave a copy of my exemption with her just in case?
