Question from Fayetteville, North Carolina, USA:

My four year old daughter was showing signs of low blood sugar while staying her grandmother’s house for a month. My mother-in-law tested her for a period of one week. Every morning before breakfast, my daughter’s blood sugar was 40 mg/dl [2.2 mmol/L], and right before lunch, it was about 70 mg/dl [3.9 mmol/L]. Her levels have never been over 72 mg/dl [4 mmol/L]and never under 40 mg/dl [2.2 mmol/L]. She has added more sugar to her diet, but she still bottoms out at night. Her urine is very strong smelling, and she wets the bed a lot even though she has been trained for two years. I have made an appointment with the doctor, but it is not for 3 weeks. Is this something i should be very concerned with? Will she grow out of it? Is there anything I can do to keep her from getting so low during the night?
