During this festive season, many of us are lucky to have the opportunity to partake in feast after feast. Unfortunately, large, rich meals can lead to super high blood sugars as your diabetic child gorges on the goodies. I'm not one to tell you to make your child pass up every tempting treat. I think that's unfair. Rather, I suggest you help guide her toward moderate portions. Most everything is OK in moderation, and you should set a good example and follow this advice for yourself too.
One tip I can't promote enough: give an insulin shot BEFORE the meal is over (or prebolus on your insulin pump). That way you get the insulin in your child's system the same time the food does. Happy Holidays!
