Overnight Advice for Low Blood Sugar

A 6-year-old boy is seen in the emergency department. He ate a large meal at 6 pm.

His blood sugar was low at 3.0 mmol/L before the meal, and has risen very slowly afterwards.

He gave himself slightly less than his usual insulin dose with the meal. Parents are concerned

because his blood sugar is not rising above 6 mmol/L, and they are worried about sending him

to bed. What is the most appropriate advice to give to parents?
