Small red bumps, itchy, no fever or other symptoms, probably eczema. Lots of kids get it, especially this time of year when the heat is on and we spend the bulk of our time indoors. The dry air dries out their skin.
Lower the temp on her bath a bit, because heat makes it worse. Someone here recommended Eucerin, and that one is pretty good. If that doesn't clear it up, try Aquaphor. I've yet to find a rash that Aquaphor doesn't clear up. Diaper rash, windburn, the rash they get from drooling, that stuff fixes anything. If you try both of those, and it's still no good, see a dermatologist for a cream called Elidel. It is made for Eczema, comes by prescription, is safe for kids, and is one of the few treatments that has no steroids in it.
Good luck!
