You might also want to try pharmaceutical grade, generic Aqueous Cream. I get them in 500g tubs at Mannings or Watson's. We slather it on the children after their bath which they take before going to bed. We also reapply throughout the day whenever their skin is dry. My husband had pretty severe childhood eczema and both children had mild infant eczema, so our family doctor recommended this since their birth as a precaution.
If you're using a heater in the children's room, try to use one with a humidifier or use it along with humidifier. You might also switch from baby soap to a non-soap cleanser, such as Cetaphil for her bath. Hot water is also more drying, so try a comfortably warm instead of hot bath. I use a heater in the bathroom so that it doesn't feel so cold even when the bathwater is only warm. Good luck!
I have extremely dry skin all-year round. Where I grew up the climate was semi-arid so I was constantly itchy and uncomfortable and went through tubs and tubs of skin cream--especially in the even drier wintertime. In Hong Kong, it's improved but winter still is pretty hard.
I totally second using the aqueous cream. I just bought two 500 g tubs at Mannings yesterday for less than $50 HKD. Aqueous cream is the base for almost all skin creams--it's good to use it because it is non-scented and scents and weird oils can really make bad skin worse.
DO NOT give your daughter HOT baths--even if it has oil in it. This is really damaging to the skin and will dry it out even more. I've had to see dermatologist after dermatologist for my own skin problems and the clear message that they hammer home every time is "LUKE-WARM water for bathing." As the weather is so cool lately, it might be hard to give a baby that cool of a bath. You might consider just giving her a sponge bath in the meantime. Unless she's really playing in the dirt and getting filthy, most babies don't need a full bath anyway. Every time you bathe you wash away skin oils--which sounds like a good thing and it probably is, unless your skin is dry and itchy.
The dermatologists I've seen also say no soap or cleansing products at all for bathing. If soap is needed get something like Cetaphil cleanser that is soap-free and use it sparingly (feet, bottom, armpits etc.). Soap and cleanser of all kinds dries out the skin.
As soon as I get out of the shower, I immediately put aqueous cream on. See, the job of a good skin cream is not really to "moisturise"--by the cream itself providing the moisture. The job of a good skin cream is to seal the moisture into the skin and create a protective layer. So, once you're wet, don't even dry off--just put on a thick layer of thick skin cream and massage the water and cream into the skin. Someone mentioned cold cream--this is a good idea because it is so thick that it seals moisture in better. I personally put on 2-3 layers of cream, massaging it in each time just to keep my skin from cracking when it gets dry.
Take it from a veteran of dry skin--unless you've got some other dermalogical problems (eczema etc.) going, on you need to use cool water for bathing, only use non-soap cleansers (sparingly) and use a good, thick, non-scented cream, often and generously.
I hope that your baby's skin gets better because dry skin is horrible!
