A short burst of prednisone is NOT a problem for a nursing mother. I would advise her to return to breastfeeding immediately and ignore the advice to wean. Also, soy formulas are not a good idea due to the huge dose of phytoestrogens they contain and their increased alumunium content. Soy protein is just as allergenic as cow milk protein, too. If a mom has to use artificial baby milk for any reason, I would much rather see her use a cow- milk based product, or if allergies are a problem in her family, a hypoallergenic/predigested product would be preferable to soy.
