Hollo, that is a very serious breach of the rules. If a child has an allergy it must be made very clear to all staff. I know at the boys' day care there is a little boy with an egg allergy and his photo is on the fridge with a huge sign saying 'Egg Allergy - NO Birthday cakes please". I would follow this up.

It does sound like she might have grown out of the allergy. I second the advice of talking to a MCHN or GP about this. It would be great if you no longer have the allergy to worry about. GL.
