Hi Spanish,
I have a 5 month old, and I know of it was me, I would probably call the dr. More than likely the dr won't care that you called. But even if they did, too bad. You are the mom and need to feel comfortable in knowing your little girl is ok. Sounds like maybe she has a little bug of some sort. Maybe just put a call in to the dr, and explain what's going on, and they can probably guide you from there. And the fact that she's doing better means if it was a bug, it's finally ran it's course and is going away. Just wondering if she had any sort of a fever? I don't think your being a paranoid mom, just a loving and caring one
