L.D.
Hello and congratulations on your pregnancy, and also on your diagnosis.
I am a mom of Celiac kids and I'm glad to tell you that the info you are getting about damage to your fetus and breastfeeding is wrong. It is really wrong. Please go to an endocrinologist who is experienced in Celiac Disease for your information. Emanuel Hospital has some good ones.
You Can NOT pass Celiac Disease to anyone in any way except genetically. If your children have the gene for CD, they already have the gene. Doesn't mean they will have active CD as you do, but they have the chance. Without the gene you will never get it. With the gene you might.
Research shows that babies with the CD gene who are breatfed resist CD for longer than babies who are bottle fed. Breast feeding is great for babies of CD parents. I don't want to give you much more info, I really think you should see a specialist and not listen to anyone (even me)who doesn't know what they are talking about.
Please go and get some appropriate, expert advice. CD does not have to be dangerous or upsetting if treated well.
