Hi, Your daughter being 8 years old, should have been have excess oil secretion which blocks the pores in the skin. That oil gets infected and causes simple acne or pustular acne. You can treat/prevent this is all 3 stages: 1.excess oil - wash with soap and water twice, avoid fatty foods (though not possible in 8 year old),use face scrubs atleast one a day 2.blocked pores - nauturally open pores and let oil pore out by applying gingelly oil, mildly before sleep. you can take steam bath atleast once, use steam vaporiser (preferably with neem and turmeric in the solution). 3.preventing infection - use turmeric to clease the face (excellent antibiotic) and/or wash face with soap and water. If severe go for antibiotics. Since the kid is 8 year old, I would suggest you try these steps, rather than hitting the kids the body with anitibiotics Hope this helps.
