Thank you Waverider!
Great links.
Also explains why my endo is ok with my BS at the moment with no meds, but told me that he will put me on insulin again when I'm trying to get pregnant again late this year (my first pregnancy I was diagnoses with diabetes at about 6 weeks pregnant - which means it was probably preexisting and was on insulin from about 12 weeks on)....
Though of course, it would seem that lower would be better anyway (if it's risk to pregnancy I imagine it's probably a risk for other things, even if less than overt diabetes..
"Does anyone know why they apply more stringent standards for diabetes during pregnancy than they do outside pregnancy?"
Here's what I found that may help answer your question.

Unfortunately MedHelp filters on occasions are too stringent with partial filtering of URL's, even medical reference sites. If the above links get blocked, I Google searched under "new born diabetes", "pregnancy and diabetes" and "diabetes care during pregnancy". And, lastly, the JAMA (The Journal of the American Medical Association) web site. You can search here for your thrush issues.
