Re: A few issues...Help!
How often are you bathing her? I realized when my daughter was a month or so that bathing her daily was drying her skin out. I started doing it every other day or less and not using any soap at all (which at this age isn't too hard since they aren't really getting very dirty). I'd just rub her down with a soft wet washcloth, making sure to get really good in her little folds around her neck and knees, etc. Then I'd dry her off and rub her all over with Cetaphil. Her skin cleared up pretty quickly.
Another thing I noticed was that any time anyone wearing perfume would hold her, she'd break out. Even if their clothes were washed in perfumy detergent. I started making sure I gave everyone a blanket before they held her so she wasn't contacting their clothes.
Oh, and regarding your bathtub, maybe it's not that it isn't clean, maybe it is the cleaning product you are using that isn't getting rinsed off well enough?
