In the morning, my son’s blood sugar is around 56 mg/dl [3.1 mmol/L]. I give him food to bring his blood sugar up to 97 mg/dl [5.4 mmol/L]. He has a hard time getting up in the morning and he is very tired during the day, even though he gets about 11 hours a sleep a night. Should I be concerned about the low blood sugars he has in the morning?

I cannot answer this on the Internet without significantly more information. It sounds like you should consult with a pediatric endocrinologist who can help decide if this is real hypoglycemia or not and, more importantly, discuss what to do to prevent the hypoglycemia from recurring. More than 90% of such children (and adults) can have their hypoglycemia prevented with proper attention to food and snack choices. Occasionally, there are very serious high insulin diseases that cause such problems, but these are much more rare than dietary-induced hypoglycemia. Specific insulin testing during an episode of hypoglycemia is needed to make such a diagnosis.
