What are the effects of high blood sugar (200+) in a lactating mother, on her infant child? Does high blood sugar = sweeter milk?

Haven't heard data. Haven't heard any data on that. Since milk production is a living process, it is reasonable to suspect that the lactose (a combination of glucose & galactose sugars) might increase if mom's blood glucose rises above a certain excessive level, and to suspect that glucose might "leak" into breastmilk if mom's glucose level is over some threshold level. Don't know if any researcher has milk this way.
