My dd has been low every night for about a month. We have changed dosages etc. I'm up all night catching and fixing lows. The biggest nightmare is when I fix, and she drops. Anyway, last night, I let her have an uncovered rice krispie treat - half. She was 125 and I let her have it. I checked her two hours later and she jumped to about 190. I checked her at midnight and she was 212. Checked her at 3A and she was 200! I then set the clock for 730AM and slep for for 4 1/2 hours with confidence. She woke up a little high, around 150. Tell me the truth, Is this a bad habit to get into?
