Hi Sparkle,
Hope your sister is doing well. There are several online resources for women with type 1 who are pregnant. Besides the pregnancy boards on diabetesforums, check out the boards (particularly Oh Baby!) on tudiabetes.org, and the site diabeticmommy.com. There are also two great Yahoo groups, PositiveDiabeticPregnancies and DiabeticMoms, both via free subscription.
I blogged about my healthy pregnancy three years ago and my current second pregnancy on my blog, Managing the Sweetness Within (www.thesweetnesswithin.blogspot.com).
For your sister, how often does she test her blood sugar? She would likely benefit from testing before every meal, an hour after a meal, two hours after a meal, anytime she feels low, anytime before driving, and before bed. Carrying a juice box, glucose tabs, or some other form of fast acting sugar would help her treat lows immediately so that she doesn't have another car accident again.
Lows are really most tough for the mom-to-be; lows don't typically affect the developing fetus unless her longterm blood sugar control, measured by a Hemoglobin A1c number, is quite low--under 4.6 or so. Research has found women with GESTATIONAL (NOT type 1) diabetes have had babies with lower birth weights with such low A1c numbers, but it is very tough for a type 1 to get that low.
And finally, I wrote "Balancing Pregnancy With Pre-Existing Diabetes: Healthy Mom, Healthy Baby" specifically for women with type 1 or type 2 diabetes who are concerned about pregnancy. It's available on Amazon and other online retailers, and I'm selling them directly through Paypal if people want autographed copies. Email me for more info at Lyrehca AT gmail DOT com.
Good luck!
