I also wanted to tell that throughout both my pregnancies, more so my first, people had all kinds of ignorant things
to say
to me, so my advice is
to not listen to everything you here or read, until you have talked to a knowledgeable person, such as an endocrinologist, midwife, obstetrician--you are getting my idea-someone knowledgeable about pregnancy and diabetes.
If you have questions have your daughter ask her doctor and follow that advice.
