Re: baby has brown staining spitup...doc says wait and see
Brown staining in spit-up is usually caused by the baby ingesting a little bit of blood with her breastmilk. It's not dangerous for her, and unless it keeps happening, it's not a problem for mom, either. What usually happens is that a tiny blood vessel in mom's breast breaks during nursing. These little vessels are fragile, but they are also resilient, and most will heal by the next time you need to nurse.
No ideas on the burping/reflux. Sorry! I hope it gets better soon, though.
