How to avoid baby getting sick


My baby is formula fed, so doesn't that mean she's more likely to get sick? I have the most awful cold, or sinus infection, or virus or SOMETHING. I can't go to the doctor until Thursday, so what steps can I take to prevent my girl from getting sick?

My husband only works the last 3 days of the week, so since he's home all day he's pretty much been on sole baby duty the last day and a half. I've been keeping my distance and making sure I don't breathe on her. Is there anything else I can do?

My main goal is to keep her from getting RSV.
