Doctors drive me crazy!

So I took Grace to the Dr yesterday and again last night. I was told: 1) She has a respiratory Virus, 2) It is early in the process (I know that is why I brought her in so it doesn't get worse) 3) It will get worse during days 5-7 4) If/When it does, bring her back. Does any of that really make sense? It is going to get worse, so bring her back, but we won't do anything now. I hate it- I just want my tiny one to feel better.
