Also, how did you handle field trips? I am inclined to NOT letting him go on field trips this little simply because there will be too many risks (other people going there, cross contamination on the bus, at eating areas, etc.). One option would be me going as well but they don't allow siblings going along and I don't have anyone to watch DS3. So unless the school would guarantee there would be a trained person going on the field trip, I am just not comfortable to let him go. Or am I taking this too far? Just as some of you, I have had far too many experiences where the allergies just weren't taken seriously and we ended up with a few very close calls.
