I would just tell my doctor I would rather try other things than take Prednisone. I flared after having my kids too, I wonder if it's common. I have only been able to calm down the flares with meds. I hope you can get out of that flare, it is soo hard to be flaring with a little baby! (I remember nursing my youngest while on the tiolet a few emergency times, what a nightmare!)
Congratulations, by the way!
