Antibiotics can throw the system off. Many doctors recommend eating yogurt or taking a beneficial bacteria supplement when an antibiotic is needed.
Also, Bubblegum Pedialyte has artificial sweetener in it which can cause gas and diarrhea.
As for the wobbling - I assume her ears have been checked? How long has she been walking? Many children will begin falling more after they get good at walking because they stop thinking about walking. But, if you are noticing that she is more wobbly I would wonder about her balance due to a possible ear infection or fluid or even possibly dizziness due to dehydration.
I know it's frustrating to keep going back to the doctors and getting no where! But, unfortunately that's what you'll need to do. Is there a different doctor you can see in your pediatrician's office? Sometimes that helps but sometimes going back to the same one and saying that the recommendations aren't helping is the best way to move forward. It helps if you write down for a day how often she is having diarrhea, what's she's eating and drinking and when she's vomiting. This will help her pediatrician see the whole picture.
Best of Luck - Stephanie
