Rheumatoid Arthritis after baby?

I have been diagnosed with rheumatoid arthritis just about two years ago, but have probably had it much longer. I went into remission when I was pregnant with my twins. I was really hoping it would kick start my body into a long term remission, but now I'm about 3 months post partum and it's starting to flare up really bad again. Just wondering if anyone else has gone through the same thing? And if you have any tips for managing? I still have to look after my girls but everything is amplified when my joints are on fire. Any suggestions would be so appreciated!
