While I agree with the cold issue and not seperating them because kids will have colds. I would like to say however that some parents send their kids with horrible coughs. Since it is pre-school you are dealing with, most likely, I am guessing that this will be a three day class. Kids with coughs should not be in school. No, not the CF cough and not the every now and then cough, I"m talking about the sickly barking kind of cough that sometimes accompanies a cold. One thing that some teachers have a hard time enforcing is the use of a tissue and covering their mouth or nose then they cough or sneeze. Take advantage to teach those little ones to make it a habit, then to wash their hands. Some teachers say this is an interuption but I will say, my sister is a kindergarten teacher and has implemented this routine into her class from her first day of teaching, 13 yrs ago. So it can be done. As someone else has mentioned, talk with the parents. If it hasn't been set up already, set up a time to meet with them before school starts so you can meet them and the student and talk about CF and what they want. Open house or "meet the teacher" and the first day of school are not good days to get that done. Try to have them bring in the enzymes before the first day of school so you are ready, everyone will be anxious that day as it is, that way nothing will be forgotten in the emotion of the first day of school. Ask them what they would like you to look out for health wise and to let them know. For example my daughters teachers would notice if they had started coughing more than usual. They would call and mention it and ask if they had come down with something or were coming down with something. And most importantly, as with most four year olds anyway, let them go to the bathroom when they need not in a minute. Lastly, depending on where you live, climate wise, keeping hydrated is extremely important if you are in a hot place. We lived in AZ when my youngest was pre-school age. Kids with CF tend to lose more salt in their sweat than a child without CF making them more suseptable to dehydration. Kids with CF have a higher fat diet in most cases so saying that cookies or pudding is bad for you is not good. My girls hated it when the teachers would say they did not have a nutritious snack because they brought pudding. (I have to say that that was something I didn't think was important to include in our meeting and that was a place where a nutritional break was taken by all classes 1st -6th grade)You are such a wonderfully caring teacher to seek out the information for your new student and to get to know their disease.
