K.,
My daughter experienced the same thing at the same age. It was a bit more difficult for me cuz I was BF and they said not to due to it upsetting her tummy more and it would also create more phlegm (just like formula). I agree with everyone else about getting a new ped! My ped said to "keep an eye on things and if I felt at all uncomfortable with the way she was feeling to bring her back to dr. office or to the ER just to make sure she was all right." She never at any point has told me why concerns were not to be worried about. she has ALWAYS asked me why I feel the way I do and then discussed things further with me on why she felt different.... than me or why she agreed with me.
We (the dr. and myself) felt one of the reasons my daughter was vomiting was because of the phlegm. She also would choke all day long. We felt this was due to the "Post nasal drip" and it was the only way she knew how to deal with it.
I did stop BF her for 4 days and just continued to feed her Organic pureed fruit/veggies and water. It really seemed to help dry things up for her. I also used Saline solution for her nose at night, put her on a incline with her mattress and then took one of her thin blankets and rolled it to lay at the bottom of her feet to keep her from sliding down the mattress so much. I did not use Pedialyte because none of my children have ever been able to "hold it down". So I just used Smart Water... it has electrolytes in it too. I also used Olive oil nose spray and throat spray for her at night before bed to help "dry things out" The saline solutions tends to make things to dry and (my children have told me this)then burn while breathing. The Olive oil dries it up as well as keeps the areas moist.
Anyway... Hope that helps you a bit!
Good Luck
