Hi Windy,
Well the frequent urination and obessive thirst are huge warning signs. Also those are pretty high spikes, since most normal people mitigate the sugar in their systems without ever getting that high.
What is good is that her A1c is low..normal. This means that her body is averaging normal for Blood sugar. What you have to do is take her readings 60 mins after eating, 2 hours after eating and 3 hours after eating and see where the readings go. If she spikes but comes back to normal within 2 hours, there probably isn't anything to worry about. Just keep her on a healthy diet is all. Let us know what the numbers are and we can steer you toward what you should be thinking about.
Also do a fasting reading in the morning after she gets up. I know its a lot of finger sticks but just for a couple of days.
