I've posted in health about my thyroid, but last night a thought struck me and has sent me into a small panic. I have antibodies to my thyroid- surely I have then passed these on to my dds through my breastmilk? My smallest dd turned 5 recently but still has a night bf. I am horrified that I may have passed on thyroid disease to her. I will ask my GP but as they are generally a bit clueless about breatfeeding I wonder who I could ask who would know- an immunologist? I am just thinking that as we pass our other antibodies on through our milk then I don't see how this would not get through.
