Have him paw through How To Raise A Healthy Child In Spite Of Your Doctor - a very up front, factual book about children and illness. In it he talks about the usefulness of fever, and allowing the body to WORK! You are right, he is wrong. Surprised? If he's around when your dd gets sick, and needs to be in charge of administering meds, I guess you have 2 choices, to allow or to fight. You will have to decide for yourself, unless you can convince him of the over-arching issue - that the body can and does fight off illness by itself tremendously well w/out meds a LOT of the time. When you need it, it's there, and it's probably important that you have chosen a very reasonable threshold of 101 to administer meds, I really think you are being very sensible. If you can convince him, all well and good. But if not, try to be the go-to for sick baby, and allow him to just be back up. Hope it works out alright for you!
