Joy, I had a doula client who has MS and insulin-dependent diabetes both. Her MS symptoms increased during her pregnancy. She had a wonderful natural childbirth and went on to breastfeed without any problems. Her MS symptoms virtually disappeared the entire first year of her baby's life. As far as I know she is still fine and still breastfeeding. Her doctors had warned her about the need to take certain drugs which would necessitate weaning. She never had to take them. Best to your client, Janaki Costello, IBCLC, ICCE, C.D. El Cerrito, CA.
