I know you are freaked. But you are a good mom and I’m sure you will be checking and logging everything. If things go south I’m sure you will get your daughter to the doctor right away. But until you actually observe really abnormal readings you will likely be dismissed by these doctors. Please consider finishing your vacation. I’m sure you will checking blood sugars. But I would suggest you simply do “watchful waiting.”
