Winter weather always dry out our skin and our dogs as well. I don't know how to help you with a quick fix unless you don't mind your baby looking a little oily for awhile. It isn't really oily, wont rub off on anything, but does look oily. Anyway for a quick fix you can add a some liquid lanolin to some conditioner that is watered down so you can just spray and leave on. In the meantime, put her on real food and give her omega fatty acid each day on her food. Like fish oil or cod liver oil.
I use the #1 All Systems Pure Lanolin Plus Skin & Hair Emollients mixed with #1 All systems Protein Lotion

When I bathe the girls, I use the # 1 All Systems super cleaning conditioning shampoo then I do a hot oil treatment on them.
