Just a thought, but check behind her ear. I was astounded to find that a cheesy smell I thought was coming from my son's ear was actually coming from a little roll behind his ear. Who would have thought? Just pull gently on the skin to flatten it out and you'll see right away if that's it. Be gentle though because if you pull too much or overdo the cleaning it might crack the skin. I think there was a thread on here awhile ago about this. HTH!
