My girls always got red, rashy cheeks when the weather got cold as younger babies. Vaseline is the best thing to use, especially before you go out as it will protect their cheeks from cold winds.
I hope that helps. God Bless, Anita
That sounds like baby eczema. Its normal with babies. I worked in day care for years in a baby room. When babies start to get teeth allot of times they get it. Show you Dr an they will give you a cream for it.
This link shows pics of it.

I know it may seen scary that your baby is growing up ;) but it's not too soon for teething, that's what it sounds like.
My ds gets that when he is teething. I have actually put diaper rash cream on it and it helped. Dont know if it is good to do that, but everytime I have used it it went away.
teething...could be it. My kids started teething at 1 month old.. Had their first teeth by 3 months.
Ummm, could be baby acne, and she may just be warm...that was my other thought
