What are these small white-like bumps on my daughters back and stomach?

See below: Without being able to see the bumps, it is hard to say. If they look like pustules, or are oozing, get seen for a possible bacterial skin infection. If not pustules and the white dots feel hard and are around hair follicles, it may be keratosis pilaris (a mild form of eczema) and treatment with exfoliating age to no steroid creams may help. See you doc for this.
