Ok so my daughter is 16 1/2 months old and I have been wondering lately if she may have the same issues I have with bowels(suspected hirschsprung's disease). Well she has either a UTI or a yeast infection right now(not sure which, she'll be seen by the dr later this week) and now today whenever she burps, its reeks like fecal matter. CAn a UTI or yeast infection cause her burps to smell that way?? Can hirschsprung's cause it if it's not accompanied with vomiting? Are there any other things I should ask the doc when she sees them, that might cause this?
