Patty it sounds as though your daughter is pretty amazing and quite strong. What is our job as mothers if we don't worry about our kids?! It's just because we love them so!
I had some unexplained complications with delivering my son, long story short, he was two weeks late and only 5 lbs, 12 oz. He spent a week in an incubator but you wouldn't know it now! He is at 14 yrs old almost 6 feet tall and solid as a brick house and in the gifted program at school! I had raynauds back then but no other suspected autoimmune disease and I took very good care of us both when I carried him.
Personally I think that autoimmune disease can effect a pregnancy if it is active but in a strong, young and healthy woman like your daughter sounds to be would not be an issue so much. Her healthy lifestyle and informing her ob/gyn is likely all that is needed to produce a healthy and beautiful grandchild.
It's so exciting too!! Gosh I love babies! I used to foster babies and my daughter is adopted. She came to us at 23 hrs old and I just never let her go! I was so blessed to be able to adopt her :)
She was born exposed and addicted to drugs. Today she is 11 yrs old and as tall as me, beautiful beyond words and smart, funny... well you just wouldn't even know the tough time she had by looking at her now!
Babies can be so resilient and strong, much stronger than we tend to give them credit for as they look so helpless and tiny. I've witnessed it personally with my own and the babies I fostered, so don't you worry!
I can't wait to hear the happy news :D
