hi @realtorladynj, Gina
for snacks, he should have a fast carb source, my favorites are skittles or even tootsie rolls, in case his sugar is too low. For a regular snack it all depends on the insulin he takes and his meal plan. a typical snack is 1 or 2 servings of carbs (about 15 to 30 grams of carbohydrates). then there are “free” snacks (zero carbohydrates). I woudl work directly with a CDE (Certified diabetes educator)
for planned snacks with carbs, I tend to like mixing the carb with a protein to slow down absorption. For example cheese and crackers. The fats in the cheese will slow down the absorption of carbohydrates from the crackers.
for free snacks, it will be harder at school because things like nuts and peanut butter may be an issue (restricted) due to nut allergies at his school and with whatever his tastes are like.
there are tons of parents on here and i hope they chime in with snack ideas as well. mine are a little bland.
