I agree the school nurse is being overbearing, and I agree with all you have said, except one. The nurse’s job is a resounding NOT to just follow doctor’s orders. We think independently of the docs in order to expedite a client’s condition to the best possible level of health that can be achieved. We learn how the various systems relate and complement or damage each other. In emergent situations, it is the NURSE who saves the patient’s life, because the doc is usually only there for a brief amount of time.
Your school nurse may be completely off base. Another angle is the nurse may be trying to learn from you, albeit in a gruff manner. Perhaps you could suggest a diabetes class for the school nurse. That way you can both work as a team to keep your daughter safe and well, instead of having a tug of war. Sometimes it is VERY difficult to work with someone who rubs you the wrong way, but there is knowledge there that can be shared in both directions.

If it were my daughter, I would not like someone appearing to try to take control from me. I am the parent, and the methods my daughter and I would use would be from ME. But, I think (think) I would try to teach the school nurse a better approach as well as the facts.
So. There’s my 20cents worth for the day.

It is off to Utah for snowmobiling!!!! How does one give a shot through a snowsuit, jeans, long johns, pantyhose?

Have an absolutely Blessed Christmas, everyone!
