expanding your family despite RA

My husband and I have dicussed having another baby around a year from now.  I am leary of this because although I had some symptoms of RA before my pregnancy, the pregnancy exacerbated the symptoms to the point of reaching the diagnosis.  I truly long to have another baby and I really want my daughter to have a sibling.  I have three siblings so I don't want her to miss out on those relationships.  When I have asked my rheumatologist about my concerns about being off my meds for the pregnancy and at least 6 months for breast feeding, he just says we will deal with it.  I know he means well but he won't have to deal with the debilitating pain, I will.  The really scary thing is that I also have a high risk pregnancy due to a clotting disorder called lupus anti-coagulant disorder.  I have had three miscarriages before my daughter.  I really don't know how well I can handle caring for my toddler,having RA without meds, and having a high risk pregnancy.  After talking with my husband I decided that no one can really tell me what to expect and therefore no one can make the decision for me.  My hubby says he cares about my health more than anything but he would love to have another child.  So here I am.  I think the benefits outweigh the risks so I think I will go for it.  My question to you all is , "is there any advice about getting pregnant and raising small children with RA knowing you have to stop the very medicine that right now I couldn't function without?"  By the way, I am finally feeling so much better.  Maybe this med combo is finally working!
