I've been adding yogurt to a hand-feeding formula so the girl I'm feeding gets live cultures...I warm it up in the microwave, because I make 2-3 days' worth at a time and refrigerate it. I just got to wondering if I'm harming the beneficial cultures in the yogurt by heating them in the microwave?? Also, if I add it to the blender...can I hurt the little cultures by blending them? Probably sounds like a silly question, but if I'm harming the little buggers, I need to find another way to get them into my bird. Thanks!
