I hope Brodie is starting to get better little by little Christa. That decision whether to go with antibiotics is a common one - with my children I dealt with it also. I agree with the "theory" of not using antibiotics when they are not completely necessary but almost every time - that viral infection became bacterial in a day or two anyway so I would often plead for the antibiotics at the start to save me a return trip and get the kids feeling better sooner!!! Plus, with Josie's possible asthma - you don't want HER exposed to these nasties!! Was she treated as well?
Hugs!!
