New and need advice !

[Inspired by Reggio]

As hard as it is to see a child in discomfort I would not apply anything not provided by the parents or with written permission for you to use something you supply - you open yourself to liability if it made it worse or an allergic reaction occurs.

If you are really concerned and wonder if perhaps he has not REALLY been seen by a DR I would draw up a "treatment form" that must be signed by a Dr that outlines the symptoms and concerns your seeing and need for clarification this is not a communal rash and what treatment for symptoms are to be offered both at home and in group care setting to ensure it is not aggravated ... that way your ass is covered and if the Dr says to avoid scented creams you can refuse to apply the one they have provided and demand one that matches the treatment plan ... win win
