i think the stats are something like 80% chance of postpartum flare in first 6 months, 30% if breastfeeding.
I breastfed, ate healthy, all of that - and had a bad flare (for me, having only had flares with sensory symptoms before) with a lot of pain, trouble walking, weakness, tremors, swallowing problems, etc.
After 3 rounds of IV steroids, one not-helpful week of IVIG infusions, and now my 6th round of tysabri, things are at bay (and I get my 6 month MRI at end of month so we'll see what's up in there.
BUT i'm sad to say i have what's likely permanent peripheral neuropathy in my feet and most of my legs : (
HOWEVER. I would NOT go back and change things because now I have my wonderful year-old vibrantly healthy child. I WOULD however, look at what they are doing in Brazil as far as post-partum steroid treatment as their relapse rates seem to be lower (saw that posted elsewhere in these forums)...
