thanks for that link! i had thought so since some of those symptoms are simliar to hers, but my doctor didn't think so (she has no problem being on her back, she doesn't vomit, just spits up a lot and is sometimes able to take large quantities of breast milk without complaint - i periodically weigh her before/after)... i may bring it up again with the pediatrician if this doesn't improve in another week because it does seem to otherwise make sense for it to be GERD
