I’m a T1 mom and breastfeeding my baby. I’ve been much more loose on my blood sugar control after giving birth to her for many reasons (first time mom, no time for myself, over one year of logging my food/insulin/BGs every day and really tired of doing it). I’m worried about nursing her with higher blood sugars. Does anyone know if mom’s blood sugars / a1c affect the amount of sugar in my breast milk? I know high blood sugars is not good for me and sometimes negatively impact lactation (i.e. volume of milk produced) but I’m specifically concerned about the sugar content / nutrition of the milk.
You should talk with your doctor and your pediatrician about this. If your baby is not diabetic then she will not probably be affected by your high blood sugar. I took a look at the NIH to see if there were any indications of sugar being increased in breast milk and could find no suggestion of it. If you are able to breastfeed, that is for sure recommended.
My wife is an IBLCE… I’ll pm you her email address, she’d be happy to answer these sort of questions.
Hi Yu-Shing,
According to the info given at this link it won’t make any difference and it will help you too since it releases hormones that help lower your bg, so you may need less insulin during this time.
I kind of suspect that the milk would be fine. I don’t know that much about it but one of my good friends was Type G (now type 2 I think, it runs in her family…) and the impression I had from what she related out of her experience was that moms are evolved to sacrifice themselves for the baby.
Thank you everyone for your responses. The Cree blog was especially useful and exactly the type of info I had been trying to find. Thanks so much!
This info is great. Wish I read it before I gave birth. My milk was late (5 or 6 days after birth). Interestingly, this conflicts a bit with the cree blog post below. This one says the breast milk will be sweeter if there is high BG whereas the other one says the breasts make milk essentially according to a formula and more sugar available in moms blood doesn’t mean more in Breast milk.
Hi phoenixbound,
The link to this website is FANTASTIC! Thank you for sharing.
I also found another link to Newborns and Jaundice. Long story short, I found out that pitocin can aggrevate jaundice in newborns and there is a higher risk of diabetic mothers giving birth to jaundice newborns.
My husband is asian- there is also an increased risk for asian newborns to develop jaundice. Asian genes tend to show more dominate than others. I have 3 kids and they were all jaundice, all required light therapy.
For my third child, I was induced with pitocin and she just happened to have the worst case of jaundice of all 3 kids. We stayed in the hospital for a week. It was horrible. Now I can share this with my OBGYN as some evidence to not use pitocin, ie do not induce me. 
Can’t thank you enough for sharing this info.
