We do something very similar, just because its Easter doesn't mean our children need to feel excluded. Andrews school phoned me for the 1st time on Friday (this will be Andrews 5th Easter) asking if an Easter Egg would be suitable because he is diabetic, my reply, you should be more concerned thats its suitable for a gluten free diet, then after much discussion i just said, any egg, so as he's not left out.
Thats the main key in any festivity, don't exclude your child just because there diabetic.
Happy Easter to all and enjoy,
