Diabetes/Celiac + Preschool

Well, today i dropped Miles off at "kindy" which they call preschool here in New Zealand, for the 2nd day, and his first day without me there. Of course i did not just "drop him off" I sat down with a few of the teachers and showed them how to check his sugar, to NOT give him anything outside of his lunch box for snack, and what signs to look out for if he is "going low." NOW, when i was signing him in, i noticed on the roster there are 50 children in his afternoon session.... whoa. I am trying not to freak out about how can they keep track of my little diabetic/celiac child with 49 other little ones... Its hard to let go of something that needs to be managed so tightly. AND then i started to think... "school is where kids get sick!!" and Miles getting sick is NOT in the question!! If he starts puking, or doesn't want to eat, we will have a serious situation on our hands, one that can lead to a hospital visit. SOO, whats a mother to do...? Hes only 3 1/2... hes still too young to know when his sugar is dropping and to warn a teacher, and he will still reach for a wheat infested cookie just like any other child. This is hard. And it gets me thinking of when one day he will go to school full time!! What then? We are not interested in the insulin pump, and that means still doing injections for meal times. Will he sit down and focus and eat his meal in the allowed 20mins after his insulin shot? Will he trade his preapproved Gluten Free lunch for treats that will make him sick?? Uggg... sorry about the vent, its too much to think about. I looked at Levi the other day and thought... "how easy and weird its going to be to just drop him off at school one day, and not worry about what he'll eat, or if his sugar gets too low... he will be a "normal kid" part of the 49 other children who just carry on with their day reaching for the wheat infested cookies and not getting sick..."
