oh wow, lots of things!!!!!!!!!!!!!! the main thing, i think, is prevention though! get her adjusted regularly, massage, etc. for prevention and if she gets sick, probiotics, simple rest and fluids and letting her body do its job. don't give her over the counter meds when she's sick, b/c it could block her body from doing its job. we don't give ours tylenol or anything, b/c fever is part of the process. if one of our kids feels hot/has a temperature, we are actually glad! it means their body is working on getting rid of that infection. i know i'm forgetting a lot of things here. BFing is a huge advantage for your dd on fighting infection. what am i leaving out, mamas?
